Mars 3D Printable Terrain – Olympus Mons, Valles Marineris & More

2026-10-27 – v2.30.0 – Fourteen More Worlds: Jupiter and the Moons of the Outer Planets

Real terrain on six new worlds: Saturn's moons Mimas (the giant Herschel crater), Enceladus, Tethys (Odysseus and Ithaca Chasma), Dione and Rhea, and Mars's moon Phobos (Stickney crater). Their elevation comes from Cassini shape models (R. Gaskell, NASA PDS), the 2024 Enceladus map by P. Schenk and W. McKinnon, and Mars Express. Heights are measured from each moon's own egg shape, so prints sit level.
Photo relief on eight more: Jupiter (the cloud tops and the Great Red Spot), Io, Europa, Ganymede, Callisto, Titan, Iapetus and Neptune's moon Triton. No spacecraft has mapped their heights all the way round, so their relief is embossed from the brightness of the Galileo, Cassini and Voyager pictures. It is not measured topography, and the credit on every model says so. Jupiter has no surface at all: you print its cloud bands.
Searchable features: craters, mountains, volcanoes and canyons from the IAU gazetteer on every new moon, and belts, zones and storms on Jupiter. The world menu groups Jupiter and its moons and the moons of Saturn.
Everything on our own server: the new worlds' elevation and surface pictures are stored on TerraPrinter's map server, not loaded from NASA or USGS sites while you work.

2026-10-27 – v2.29.0 – Laser-Scanned Terrain in the US and Canada

Small models in the US and Canada now use laser-scanned (LiDAR) ground. When a model covers a few kilometres or less, the terrain comes from USGS 3DEP (US) and NRCan HRDEM (Canada) bare-earth elevation at 2–10 m instead of the 30 m grid, so streets, levees, river banks, ravines and small hills show up, and downtown ground is real street level instead of an estimate. Gaps blend smoothly into the usual data, and everywhere else nothing changes. The download dialog says when it was used, and the data credits are added to the file.

2026-10-27 – v2.28.0 – Better Roofs on Houses

Row houses get one roof: terraced streets, semis and canal houses that share walls now get a continuous ridge along the row instead of a separate little hip on every house. Tall narrow canal houses face their gables to the street.
L, T and U-shaped houses: each wing gets its own ridge, and the ridges meet in proper valleys instead of one odd roof squeezed over the whole outline.
Regional roofs: in places where houses mostly have flat roofs (North Africa, the Middle East, India, Mexico, the Greek islands and more), untagged houses now come out flat.
Barns, churches and small apartment blocks without roof tags get a pitched roof too: lower on barns, steeper on churches.
Fewer stray open edges on pitched roofs in the mesh check.

2026-10-27 – v2.27.0 – Wall Maps Are a Gift

New gift: wall maps. Frame a city, a neighbourhood or a lake and make it three ways: a multi-colour plaque to 3D print, a real-size SVG for your laser (one engraved board, or two layered boards with the water cut out), or a print-ready poster. Streets, buildings, water, parks and lettering each get their own layer. It opens from the Gifts menu, the gift cards and the tool strip on every gift page, carrying over the place you're looking at.

2026-10-27 – v2.26.0 – Seller Dashboard

New seller dashboard for people who sell what they make (it's all free to sell). It's free, and private to your account.
Save gift designs: every gift maker has a Save to my designs button. Your saved gifts show up next to your map models, with a picture of each. Open one to carry on where you left off, tag it, or make a copy with a different engraved name for a custom order.
Products and profit: turn a design into a product with a price, and enter the filament, print time, packaging, shipping and platform fees. Profit and margin update as you type. Set your filament price, printer cost per hour and Etsy, Shopify and in-person fees once in Settings.
Orders and print queue: add sales by hand, with the customer's first name, the order number and the name to engrave. Move them from To print to Printing, Shipped and Done. Open design opens each order's design with its engraved name already filled in.
Import from Etsy and Shopify: upload Etsy's “Sold Order Items” or “Sold Orders” download, or a Shopify orders export. You see every row before it's added. Items are matched to your products by SKU, then by name, and orders you've already imported are skipped. Addresses and emails in the file are never stored.
Sales stats: revenue, costs, fees, profit, order count and average order for any period, a month-by-month chart, top products and sales by channel. Export your sales as a CSV for bookkeeping and taxes.
Listing kit: the “Made with TerraPrinter (terraprinter.com)” credit and the data credits for each tool, ready to copy into your listings.

2026-10-27 – v2.25.0 – Keychains Have Their Own Maker

New keychain maker: pick a place on the map and get a 15–50 mm keychain with the real terrain, the bigger buildings and roads, water and parks, a tab or a hole for the key ring, and a name engraved on the back. Choose a square, rounded or round shape and watch it update in 3D as you go.
Download it as an STL, or as a 3MF with the base, terrain, buildings, roads, water and parks as separate colour parts. Every part is a closed solid, with nothing thinner than 0.6 mm and a 4.5 mm ring hole with at least 2 mm of wall round it.
The Keychain switch has moved out of the app's settings. Old keychain links open the new maker on the same place, size, ring and name. Open it from the Gifts menu to start on the map you're looking at.

2026-10-27 – v2.24.0 – Real Trees

Trees from OpenStreetMap: every tree mapped in OpenStreetMap prints where it stands: cones for conifers, round crowns for broadleaf trees and palms, sized from their real height and crown where they're tagged. Mapped tree rows along streets and canals get trees spaced along them.
Woods and parks: trees are scattered evenly through woods, forests, orchards and parks (more thinly in parks, and not on lawns, pitches or playgrounds), kept off buildings, roads, rail and water, and inside the model's outline.
Forest canopy: when a forest is too dense to print tree by tree at the model's size, it prints as a bumpy forest canopy. Choose Automatic, Single trees or Forest canopy under Trees.
Prints cleanly: every tree is one closed solid at least 1.2 mm across and 1.6 mm tall, with a flat foot sunk into the ground and no overhang flatter than 45°, so it prints without supports on a 0.4 mm nozzle.
Own colour: trees are their own part in multi-colour 3MF files. With Surface colours on, they share the forest colour so they don't need another filament. New Tree size and Max tree height settings.

2026-10-27 – v2.23.0 – Real Bridges and Building Heights

Bridges print as bridges: an arched deck from bank to bank with open space underneath, piers no more than about 12 mm apart so it prints without supports, and railing lips along wide decks. Water stays visible under bridges and valleys keep their real shape under viaducts.
Sidewalks and cycle paths on a bridge now run at the road's height instead of dropping towards the water, and bridges that OpenStreetMap splits (Tower Bridge's road through its towers, the Golden Gate's sidewalks) stay one deck.
Over 90 million buildings with no height in OpenStreetMap now take their height from Overture Maps (measured heights first, then estimates from aerial imagery) before falling back to a guess from the building type or footprint. The 3D map preview uses the same heights. Credited in the download and on the license page.

2026-10-27 – v2.22.3 – Open in Your Slicer

New "Open in…" button in the download window: send your model straight into Bambu Studio, OrcaSlicer or Cura (5.7 or newer) with one click, colours included, without saving and importing a file. Your choice of slicer is remembered.
Bambu Studio asks once whether to open a file from terraprinter.com: choose Yes. PrusaSlicer only opens links from its partner sites, so for PrusaSlicer the 3MF is downloaded instead.
If the slicer doesn't open (for example, it isn't installed), the button offers the normal download instead.
To make this work, the 3MF is uploaded to our server and deleted after one hour. Downloads still never leave your computer.

2026-10-27 – v2.22.2 – Sentinel-2 Satellite Map

The satellite map now shows Sentinel-2 cloudless imagery (EOX, CC BY 4.0) everywhere: the main app, the classic version and Drive. It is sharp enough for mountains, coastlines and regions, but softer than before when zoomed into a town.
Street and topographic maps in the classic version and Drive now come from CARTO and OpenTopoMap.

2026-10-27 – v2.22.1 – Satellite Colours From Sentinel-2

Satellite surface colours and the satellite drape in the 3D preview now come from Sentinel-2 cloudless imagery (EOX, CC BY 4.0), so models coloured from satellite imagery are clear to sell. The credit is added to the download. The satellite map you browse on is unchanged.
Classic version: the satellite texture in GLB downloads uses the same Sentinel-2 imagery.

2026-10-26 – v2.22.0 – Chocolate, Soap and Candle Molds

Molds of real places: cast a mountain in chocolate, an island on a bar of soap, a canyon in concrete, peaks as ice cubes or Fuji as a candle. Print a master and a slide-together mold box for food-safe silicone (with the silicone you need in ml, grams and cost), or print the mold itself for soap, wax, concrete, plaster or resin. Chocolate bars of the Alps, Seven Summits pralines, detail matched to each material, a cast preview in the real material and a printable instructions card.

2026-10-26 – v2.21.0 – Cookie Cutters

Cookie cutters: a mountain skyline, a country, state or province, a city outline or a classic shape as a printable cutter, with a stamp that presses the real terrain into the dough (mountains raised on the baked cookie). Outlines are smoothed for dough, with a before/after view; optional mirrored text, border and bridges; fondant setting; baked-cookie and 3D previews; STL, 3MF and a print-ready plate.

2026-10-26 – v2.20.0 – Terrain Ball Runs, Carved Grooves & a New Landing Page

Ball run Terrain mode: pick any mountain and the track is designed from the terrain, spiralling round the peak, over saddles and through short tunnels with windows, for as much track as the print can hold (about 2 m on a 220 mm bed with an 8 mm ball). Presets: Fuji, Matterhorn, Tre Cime, Vesuvius, Grand Teton, Table Mountain. Links from the app open in Terrain mode.
Carved style: no separate track, just a groove cut into the terrain with soft banks, a dish for the finish and an optional accent-colour groove part. Default in Terrain mode.
Ball's-eye and chase cameras ride through the tunnels, with a lit bore and a bright portal ahead.
Elevation spikes in some tiles (pits down to −9.5 km near Cape Town) are smoothed out.
Landing page: 16-feature toolkit, Makers section, 10 formats, links to place pages and the current app.

2026-10-25 – v2.19.0 – Mountain Ball Run

Mountain ball run: a famous mountain road, ski run, trail or your own GPX ride as a 3D-printable ball run. A steel ball rolls down the real hairpins, in order, to a finish cup. Drop the ball in 3D first (chase and ball's-eye cameras), then print it. Presets include the Stelvio, Alpe d'Huez, Trollstigen and Lombard Street; choose a ball from 6 mm to ½" steel or a glass marble, and add a magnet pocket in the cup.
Rivers and streams from the map now guide the watershed maker, and can be drawn on the basin map.

2026-10-25 – v2.18.0 – Star Maps, Shadow Boxes, Useful Objects, Watersheds and Data Sculptures

Five more makers, free in your browser:
Star map and place: the night sky over any place at the minute you choose (with the Moon in its real phase), and the place itself on the back as terrain or a street map. Plaque, glowing lithophane, poster or laser file.
Backlit shadow box: a city skyline or a mountain range cut into 3–6 layers that stand one behind the other in a printed box, lit from behind by an LED strip. Print it or laser cut it.
Bookends, vases, boxes and lamps: bookends that hold a real mountain range between them, a vase or pen pot wrapped in a 360° skyline (vase mode ready), a keepsake box with a map lid, and a lamp shade that glows with the view.
Watershed models: where does the rain go? Rivers carved in, wider where more water flows, and each drainage basin in its own colour, or click a river to see its whole watershed. Linked from the classroom kit.
Data sculptures: countries, US states or Canadian provinces raised by any number you paste in, or your own points and GPX tracks as a 3D heat map. Your data stays in your browser.
Gifts in the app: a Gifts button in the top bar, a gift card at the top of the settings panel and a "Make it a gift too" row in the download dialog. Each opens the maker on the place you're looking at.

2026-10-25 – v2.17.0 – Gift Makers and a Free Commercial License

Six new gift makers, each made for one kind of gift, all free in your browser:
Map ornaments: hometown hearts, mountain stars, baubles and mini globes with a hanging loop and names engraved on the back.
Layered contour models: a mountain, lake or island as stacked contour slices to laser cut or print, numbered so they stack in order.
Race medals and trophies: load a GPX or TCX and get a medal, keychain or trophy with your route on the real terrain and your time engraved.
Mountain jewellery: rings in real ring sizes, pendants, earrings and cufflinks carrying a real ridgeline, or the skyline traced from a spot you pick.
Your home in 3D: search an address for a desk model of the house with its roof, neighbours, street and a name plate.
Coasters and wall tiles: one map split into coasters or a wall grid whose pieces line up exactly.
Free commercial license: everything you make is free to use and sell, prints and files alike. Just credit terraprinter.com and keep the data credits, which are now written into every download.
Faster map data: parks no longer pull two huge Alaska reserves into maps between about 51° and 71° north, so those areas load much faster.

2026-10-25 – v2.16.0 – Laser Cut Map Art

New in the map art studio: laser files. Turn any design into an SVG for a laser cutter, drawn at real size in millimetres, 80–600 mm wide.
Engraved board or layered boards: Engrave the whole map on one board, or cut the water out of a top board and stack it on a base board whose engraved water shows through.
One colour per job: Red cuts, blue scores, and roads, buildings, water, parks and lettering each engrave in their own colour, so LightBurn, xTool or Glowforge give each its own power and speed.
Your choice of roads: Engrave them at full width or score them as thin lines for a faster job. Cut along the whole sheet or just the circle or heart.
A wood-tone preview shows the boards as they come off the laser.
Faster studio: Sliders and typing in the art studio are now smooth on dense cities, and moving the map redraws up to 10× faster.

2026-10-25 – v2.15.0 – Map Art Studio

New: Map art studio. Frame any city or place, pick one of nine styles (ink, blueprint, neon, atlas, sumi, Bauhaus, pastel, topo or noir), change any colour, and add a title, subtitle and coordinates.
Poster: Download it as a 300 dpi PNG, an SVG or a PDF for A4 to A2 or 8×10 to 24×36 in, in a rectangle, circle or heart.
Wall plaque: The same design as a 3D-printable plaque, 100–250 mm wide: each colour is a raised step, as named parts in a 3MF for multi-colour printers, with the filament-swap heights listed for single-colour printers. STL too.
Every design lives in its link, so you can bookmark it or share it.

2026-10-25 – v2.14.0 – Sea-Level Time Machine

Sea-level time machine: A new Sea level slider prints any coast as it was in the last ice age (about 120 m lower, 20,000 years ago) or as it could be in the future, up to all the ice melted (about +70 m). The new sea prints flat in its own colour, as a separate part in 3MF downloads.
Only where the sea can reach: Land floods only if it's connected to the sea, so dry basins like Death Valley stay dry (or flood every low spot with one tick). Lower levels use sea-floor data to show land bridges like Doggerland and Beringia.
Globes too: Coloured globes show the ice-age or flooded world, with the sea and land colours following the new coastline.
See it before you print: A blue tint on the map previews the new sea, quick links jump to Doggerland, the Bering Strait, Florida, the Netherlands and Bangladesh, and the name plate can show the level, like "–120 m · Last Ice Age".

2026-10-25 – v2.13.0 – Lithophane Maps & Moon Lamps

Lithophanes: Turn any area into a thin panel whose picture glows when light shines through it: rectangle or round, 50–250 mm wide, with an optional frame, hanging loop, gentle curve and a stand. It prints standing up in white.
Moon lamps: Print the whole Moon, Mars, Earth or any other world as a glowing lamp. It prints in one piece without supports, with an opening underneath for an LED tea light or puck light, and a stand to sit on.
Pictures: Relief shading or height from the elevation data, or on other worlds NASA's own photos of the surface. Adjust the contrast and brightness, or invert it.
Light on: The 3D preview shows the print lit from behind, so you see the glowing picture before you print it.

2026-10-24 – v2.12.0 – Golf Courses & Faster Route Search

Golf courses: Search any of 37,000 courses by name and print it with fairways, greens, tees, bunkers, rough and water hazards in their own colours, plus flagsticks and hole numbers. The new Golf course preset frames the course and puts its name on the label.
Faster route search: Hiking, cycling and running routes (nearly 400,000 of them, marathons included) now come straight from TerraPrinter's own map database, so search is instant and long trails like the Appalachian Trail show up as one route.
Ski runs now load from the same database: 115,000 runs and 28,000 lifts worldwide.
Sharper globes: A new Detail setting prints globes with up to three times finer relief, and the download preview shows the assembled globe.
Smaller 3MF files: 3MF downloads are now compressed, so they're about five times smaller and quicker to download.

2026-10-24 – v2.11.0 – Globes, Memory Pins & Ski Runs

Printable globes: Print Earth, the Moon, Mars or any other world as a 60–200 mm ball with raised mountains and craters. It prints in two hollow halves that line up with filament pins or magnets, with sea, land and high ground in their own colours.
Memory pins: Mark the places that matter (where you met, your first home) with a heart, star, house or pin in its own colour, and print their names and dates on a legend in front of the model.
Ski runs: Ski runs coloured by difficulty, in European or North American colours, plus the lifts as dashed lines. One click jumps to Whistler, Zermatt, Vail, Chamonix or Niseko.

2026-10-24 – v2.10.0 – Keychains, Shapes, Frames & More Formats

Keychains: Make a small 15–50 mm model with a ring tab or a hole, and an optional name engraved on the back. Tiny details are dropped so it prints cleanly.
New shapes: Heart, star, rounded square, shield and oval, a word cut to its letter outlines, your own SVG, or the outline of a searched city or district.
Better frames: Chamfered, rounded, stepped, cove and ogee edges; a separate drop-in frame; keyhole slots for hanging on a wall; and frames around grid tiles.
Height bands: Colour the terrain in 2–12 elevation bands (and blue depth bands for the sea floor), each its own filament.
Routes: Search hiking, cycling and running routes and add them to your model, with route height and width per route.
Puzzle extras: Numbers under each piece, and a tray with the numbers in its floor.
More formats: A PNG picture (up to 4096 px, studio or transparent), a DXF outline for laser cutters and CAD, a GeoTIFF elevation grid, and a Bambu Studio 3MF option with one part per filament.
AI assistants: Ask for a landmark by name and get a model with the detailed 3D landmark included.

2026-10-23 – v2.9.0 – Large Projects & the Live Globe

Large projects: Print an area up to 500 km × 500 km (an island, a mountain range, a coastline and its sea floor) as a grid of tiles that each fit your printer. Pick the globe button in the toolbar. Every tile shares the same scale and base height, and neighbouring edges are made to exactly the same heights, so the tiles meet flush even when you print them weeks apart. Tiles are named A1, B3… on the map, and you can type in exact coordinates.
Plan by the finished size: Enter how wide you want the finished piece (cm, m, inches or feet) and pick your printer; TerraPrinter works out the tiles. It warns when the tallest tile won't fit your printer's height, with a one-click fix, and estimates the filament and printing time for the whole project, split across however many printers you have.
See it all first: Preview the whole project in 3D shows the finished piece with its tile grid before you print a single tile.
Save all tiles at once: Make every remaining tile in one go, saved into a folder (Chrome and Edge) or a ZIP file, with a layout.txt guide showing where each tile goes and a folder per printer. The progress window shows the time left, keeps your screen awake, and can be cancelled at any time (or press Esc); tiles already made are kept.
Easy to assemble: Each tile gets its label and a north arrow cut into its bottom, and can have holes for alignment pins made from 1.75 mm filament.
Pick up where you left off: The project link keeps which tiles are done, and signed-in users can keep the project in My builds, updated as tiles are finished.
Live measurements while drawing: The area in the bottom bar updates as you draw, resize or move a shape and turns red past the size limit. Rectangles and squares also show their width × length.
Resize from any corner: Rectangles and squares have a handle on every corner (the opposite corner stays put, even when rotated), hexagons on every point and circles on four sides.
Too big? Switch in one click: Drawing an area larger than one model can cover now offers to switch to Large project mode, keeping your shape.
Site name underneath: Models now have a small terraprinter.com engraved into the bottom face, hidden when the print is on display, so people who pick it up can find the tool. Turn the 3D preview over to see it. Small pieces (down to about 4 cm across) get it on two lines, it stays clear of magnet pockets, and Large project tiles carry it under their label. Switch it off under Print & model.
Download from the 3D preview: The full-screen preview now has Download 3MF, STL, GLB and OBJ buttons along the bottom, plus a light from underneath so you can see the bottom of your model.
Get your shared model found: The Share window has a new Let search engines show this page switch, off by default. Turn it on for famous places, so people searching for them can find your model. Shared pages also link to ready-made 3D maps nearby.
Real ground in big cities: The elevation data includes rooftops, so dense downtowns like Lower Manhattan showed invented hills up to 150 m high with every tower perched on top. Where the map has buildings, TerraPrinter now works out the ground underneath them, so city models sit on their real streets, while real hills (like San Francisco's) keep their shape.
Cleaner city streets: Roads are now printed by size, so highways and avenues stand out from side streets. Sidewalks, crossings, plazas and parking aisles are no longer drawn as extra lines beside every road, so a city like Lower Manhattan goes from about 130,000 street triangles to about 16,000. Nothing underground appears any more, including tunnels, subways and indoor walkways. Bridges now cross rivers and roads on a level deck held up by piers.
Roads stay on top: Roads, trails, rail, contour lines and GPX routes no longer sink into the ground on hills. They now follow the terrain between map points and sit above it across their full width, so they print as unbroken lines instead of dashes.
Faster to load and use: The map draws fewer pixels on high-resolution screens, libraries load without holding up the page, the ZIP and AR tools load only when you use them, and the welcome tour appears straight away for first-time visitors.
Fixes: Grid-mode links reopen in grid mode, and a shape that's too large no longer stays drawn on the map after it's refused.

2026-10-22 – v2.8.0 – Landmarks & Share Any Model

3D landmarks: 32 hand-modelled landmarks, including the Eiffel Tower, CN Tower, Taj Mahal and Empire State Building, replace the plain blocks from the map when they're inside your area, on their real footprint. Turn them off under Overlays. Browse them all in the landmarks gallery and download one on its own, with an optional name plate.
Hide tiny buildings: A new slider leaves out buildings too small to print well, with a count of how many were hidden.
Share any model: A Share button in the download window and the 3D preview makes a short link with a designed picture of your model (place name, size and style), ready for Reddit, Facebook, LinkedIn and more. You can rename it before sharing.
2D / 3D toggle: The top-down button now switches between a flat map and your 3D view, and remembers your tilt and rotation.
Join the community: An r/terraprinter link in the About section.
Tidier on phones: How to Use, r/terraprinter and Suggest a feature share one More menu in the top bar.
Fixes: Name plates on frames no longer print upside down, and Download for Minecraft only appears for Minecraft-style models.

2026-10-20 – v2.7.0 – Minecraft Worlds & Sharper Blocks

Download for Minecraft: Turn any area into a Minecraft world. Download for Minecraft (.schem) in the download window builds real blocks (grass, stone, snow, water, roads, rails and buildings) up to 512 blocks across, ready to paste in with WorldEdit.
Sharper Minecraft prints: Choose how many blocks across (32 to 256, now 120 by default) instead of a block size in millimetres; blocks can be as small as 0.8 mm.
A Minecraft look in the preview: Pixel block textures, a dark grid floor and the world's size in blocks.
Blocky map features: In Minecraft style, water, roads, trails and rail become block tiles and buildings become stacks of blocks. Lakes sit level, one block down in their own basins. Picking Minecraft starts with only water on, for a clean block look.
City maps print flat: The ready-made city models (Manhattan, Paris, Shinjuku and more) now open as flat models, so the buildings and streets stand out. Rio, Hallstatt and Hong Kong Island keep their mountains.
Menus in your language: Dropdown choices, preset names and remix notification emails are now translated too.
Accurate checks for Minecraft models: The download window now shows the right filament estimate and no false "open edges" warning.
Always secure: Every link now opens over HTTPS on terraprinter.com.

2026-10-20 – v2.6.0 – Hollow Bases, Magnets & Five New Languages

Hollow base: Under Print & model, hollow the model out from underneath to save filament. The roof inside follows the terrain and slopes steeply enough to print without supports; tall mountains use roughly a quarter to a half less filament.
Magnet pockets: Add round pockets in the bottom for disc magnets (6 × 2 mm to 12 × 3 mm) so models stick to a fridge or steel board, and tiles and puzzle pieces line up.
Five new languages: TerraPrinter is now in Italian, Portuguese, Polish, Japanese and Simplified Chinese at /it/, /pt/, /pl/, /ja/ and /zh/, alongside English, German, Spanish, French and Russian.
A new download window: After you generate, a live preview you can spin, one clear Download 3MF button, the other formats underneath, readable counts of what's in the model, and the filament, cost and time estimate. One STL per colour now lives in the arrow next to STL.
Saving is up to you: Generating no longer saves to My builds by itself. Choose Save to My builds, or Save changes / Save as new when you edit a saved build.
Your printer and presets: Pick your printer under Print & model and TerraPrinter warns when a model won't fit, with a one-click split into tiles that do. Save your favourite print settings as presets (synced to your account when signed in).
Better surface colours: Snow above the snow line and rock on steep slopes are added automatically, tiny colour specks are cleaned up, colours are capped to your filament slots, and a legend shows what's on the model.
Rivers and lakes: Rivers mapped as areas now follow their valley instead of disappearing into it, and mountain lakes sit flat in their basins instead of standing up as raised blocks.
Minecraft style: Roads, water and buildings now sit on top of the blocks instead of floating or sinking.
One-click downloads: Every 3D map page has Download STL and Colour 3MF buttons that build and download the model straight away.
Community prints: Photos of real prints now appear on place pages, a print photo wall collects them all, and a print of the month is featured. Creators can get an email when someone remixes and shares their build (turn it off any time).
New guides: 3D map gift ideas and free classroom lesson kits, both linked from the About section.
A cleaner look: Quieter panels, clearer headings, the logo on every screen size, a tidier About section, and AR only offered on phones and tablets.

2026-10-19 – v2.5.0 – Six New Worlds & Models From Your AI Assistant

Six new worlds: Print Mercury (Caloris Basin, the great scarps), Venus (Maxwell Montes, Maat Mons), Pluto (Sputnik Planitia, the ice mountains), its moon Charon, and the dwarf planet Ceres and giant asteroid Vesta from NASA's Dawn mission. Each has real spacecraft elevation and surface imagery, named-feature search and one-click picks under Locations, plus 52 new ready-to-print pages in the 3D maps gallery. Pick them from the world button next to the search bar. (On Pluto and Charon only the side New Horizons flew past is mapped in detail.)
Ask an AI for a model: Tell Claude, ChatGPT or another assistant something like “make me a 3D print of Mount Fuji”, and it replies with a link that opens TerraPrinter and generates the model, ready to tweak and download. Add the TerraPrinter connector to Claude, or the actions to a Custom GPT; the AI assistants page shows how.
Shareable make links: Links like terraprinter.com/make?place=Matterhorn build a model of any place, coordinates or crater on Mars and the Moon, with optional size, shape, layers and exaggeration.
Suggest a feature: Have an idea? Tap the 💡 button next to the help button, or visit /suggest/. No account needed and your email is optional; we'll only use it if we have a question.
Water on by default: Lakes, rivers and the sea now show on the map and in new models without switching them on. Turn them off from the OSM chips if you want bare terrain.
Privacy policy: A new privacy policy explains what we collect, why, and how to have it deleted. The footer also links to it, the AI page and feature suggestions.

2026-10-05 – v2.4.1 – Puzzles That Actually Fit

Clean puzzle pieces: Each piece's terrain now runs right up to its walls, with smooth knobs and sockets. No more stepped edges, raised rims or holes in the knob tips.
Seamless joins: Neighbouring pieces match in height along every edge, and all pieces share one colour scale, so the assembled puzzle reads as one model.
Map features split per piece: Buildings, roads, trails, water and GPX routes are cut to each piece and stay inside its outline, including in 3MF exports and Build Puzzle.
Much faster: Features are fitted to the pieces once while generating, instead of freezing the preview and every export. Puzzles on Mars and the Moon build quickly too.
Better preview: Puzzles open with the pieces pulled apart (toggle to see them assembled), and Build Puzzle uses the same elevation colours as the app, with smoother shading.
Watertight models: Every model and puzzle piece is now a fully closed solid, with no open edges or holes where the sides meet the terrain, so slicers don't have to repair anything.
New Locking edge: Pick Locking under Puzzle → Edge style for classic necked knobs that hold printed pieces together; they only come apart by lifting. A new Fit gap slider (default 0.24 mm) spaces every edge style so printed pieces slot together without sanding.
Puzzle music: The Puzzle Playground has an optional ambient soundtrack. Tap Music in the toolbar; it remembers your choice.
Globe view removed: The map now always uses the flat view, which keeps 3D terrain and drags smoothly. The globe couldn't show terrain and was awkward to move around.

2026-10-04 – v2.4.0 – Print Mars and the Moon

Two new worlds: Switch between Earth, Mars and the Moon from the new button next to the search bar. Draw an area and generate a printable model exactly like on Earth.
Real NASA elevation: Mars uses MOLA laser altimetry (463 m), the Moon uses LRO LOLA (118 m). Sizes are true to each body, so a 200 mm Olympus Mons is really 600 km wide.
Search every named crater: Find over 2,000 features on Mars and 9,000 on the Moon from the official IAU gazetteer, plus one-click picks under Locations: Olympus Mons, Valles Marineris, Gale and Jezero craters, Tycho, Copernicus and the Apollo 11 & 15 landing sites.
Bigger areas: Select up to about 2,000 km across on Mars and 1,000 km on the Moon. A Relief basemap shows the height colours, and relief starts at 4× exaggeration so craters and volcanoes stand out.

2026-10-04 – v2.3.1 – Water Sits Level With the Land

No more raised lakes: Lakes, reservoirs and the sea now sit at their real water level, flush with the shoreline, instead of standing up like a slab with walls. Small ponds no longer poke up as blocks on hillsides.
Still prints as its own part: Water stays a separate, coloured part in 3MF exports for multi-colour printing. Want it raised? Turn up the Water depth slider under Colors & feature scale.

2026-10-03 – v2.3.0 – 3D Maps of 330 Famous Places, 5 Languages & Real Oceans

330 ready-made 3D maps: The new 3D maps section has a page for famous mountains, volcanoes, canyons, lakes, islands, fjords and city skylines — Mount Rainier, the Matterhorn, the Grand Canyon, Manhattan, Hong Kong and many more. Each shows a rendered preview, real elevation figures and printing tips, with one click to Generate & download or open it to customise.
TerraPrinter in your language: The app and all new pages are now available in Deutsch, Español, Français and Русский. Switch language from the settings panel.
Oceans that work properly: The sea now shows around islands (Stromboli, Heligoland, Santorini…), harbours and bays no longer disappear under the land, and island coastlines are no longer mistaken for water. Coastal models look and print the way you'd expect.
Lakes and rivers on the 3D maps: Place pages and their downloads now include water, so lakes, rivers and reservoirs show up in blue.
Show off your print: Add up to 4 photos of your real print to a build. They appear on its public page and in the gallery's new Printed tab.
Easier sharing: Share builds to LinkedIn, and copy a ready-made description (with the map-data credits) for posting your print on Printables or MakerWorld.
Fixes: Mount Ararat and nearby areas, where the main elevation dataset has a gap, no longer come out flat. Very large, dense areas (big lakes, whole cities) no longer fail to load map features. Build thumbnails are framed tighter.
New pages: a FAQ, and a Map2Model alternative guide for anyone moving over from Map2Model, which has shut down.

2026-09-24 – v2.2.0 – Free Accounts, My Builds & Community Gallery

Free accounts: Sign up with an email and password — no cost, no paywalls. Every model you generate while signed in is saved automatically to My builds.
Edit and re-download anytime: Reopen any saved build to tweak its settings, or use Generate & download to rebuild it and download STL, 3MF, GLB or OBJ again.

Community gallery: Browse what others have made in the gallery — featured, newest and most popular — like your favourites, and remix any of them into your own print.
Your public name: Choose a display name for builds you share; your email is never shown.

2026-07-14 – v2.1.0 – Surface Colours for Multi-Filament Prints

Colour the terrain surface itself: A new Surface colours option splits the terrain skin into printable colour regions — each printing as a thin coat welded onto the base terrain on its own filament. Built for modern AMS / MMU / toolchanger printers that handle 6, 8, 10+ colours, so a terrain model comes out realistic and recognisable instead of one flat colour.
Two colour sources: Colour by OSM land-cover (forest, grass, rock, sand, glacier — each with its own editable colour and on/off toggle), or by Satellite imagery, which reduces the real satellite photo of your area to a handful of filament colours and paints the surface to match.
Pick your palette: In satellite mode, choose how many colours to use (2–12) and the palette is extracted automatically from the image — then recolour any swatch to match the exact filaments you have loaded, with the preview updating live.
Smooth, print-ready edges: Colour boundaries follow the real land/scene outlines with clean diagonal transitions rather than blocky squares, and each colour exports as its own object in the multi-material 3MF so slicers pre-assign every region to a filament.
Multiple GPX routes: Import several hikes/rides at once — each route embosses as its own raised ridge in its own colour and prints on its own filament, with a routes list to recolour or remove any of them.

2026-06-17 – v2.0.2 – Accurate Roofs, Correct Orientation & Fixes

Accurate roofs: Buildings now print with their real roof shapes from OSM — true hipped roofs (ridge + sloped ends), skillion mono-pitch slopes, real domes, and pyramidal/gabled forms — oriented by the roof:direction / roof:orientation tags. Parliament Hill, churches, and detailed buildings read correctly instead of as flat boxes or pyramids.
Fixed mirror-flipped models: Generated models were a mirror image of the real world; they're now correctly oriented (and so are every STL/3MF/GLB export).
No more floating parts: Elevated building parts (rooftop structures, mechanical penthouses) no longer hover in mid-air — the supporting mass beneath them is kept.
Water reads as water: Sea-floor relief and the water surface now sit at a visible, printable height by default instead of being flush with the riverbed.
Cleaner edges: Removed stray geometry that could appear outside circular, hexagonal, and freehand model boundaries.
Size cap on resize: The 120 km × 120 km limit now applies when resizing or reshaping a selection, not just when drawing it.
Curated default view on load, with buildings, roads, trails, and railways enabled (water & parks off).
Live map buildings render as clean white massing with all building parts, and the tiles cache faster.
Plus a batch of polish: softer preview lighting so deep recesses don't look like gaps, a single "Classic version" link, and analytics fixes so every model generation is counted again.

2026-06-17 – v2.0.1 – Live Simple 3D Buildings, Redesigned Settings & Branding

Simple 3D Buildings in the live preview: The on-screen map now renders building:part massing — towers, spires, tiered roofs, arches — so the preview matches the printed model instead of showing flat-topped boxes. Part footprints that replace a base outline are dropped, and raised parts sit at their correct min_height.
Redesigned settings panel: The long settings list is now organised into collapsible accordion groups (Map & lighting, Terrain & style, Print & model, Colors & feature scale, Overlays, Multi-tile, Custom buildings, Locations, About) so it's far easier to scan.
Sea-floor relief, promoted: The bathymetry toggle is now a prominent switch pinned to the top of the panel instead of a buried checkbox.
Branding & polish: Added the TerraPrinter logo + wordmark to the top bar, made the rectangle the default drawing tool, and hide the settings gear while the panel is open.

2026-06-16 – v2.0.0 – TerraPrinter v2: MapLibre Globe Edition

Instant live 3D preview: A ground-up rebuild on MapLibre GL. Terrain, hillshade, and 3D building extrusions render live on the GPU as you pan and zoom the whole planet — no more waiting for a model to generate just to see your selection.
Globe projection: Switch between Mercator and a true 3D globe view.
Live OSM overlays: Buildings, water, parks, roads, trails, and railways stream in as vector tiles from our planet-scale Postgres mirror, each independently toggleable on the map.
Interactive sun compass: Drag the sun around a sky-dome to set hillshade azimuth and altitude, with a live warm/cool sky that tracks the sun's height.
Terrain styles: Realistic, Puzzle (interlocking pieces), and Minecraft (voxel blocks with sand/stone/snow levels).
Per-feature print scale: Independent height (and width, for lines) multipliers for buildings, roads, trails, rail, water, and parks so every layer prints legibly.
Sea-floor relief (bathymetry): Carve ocean and coastal depth into the base for islands and coastlines.
Elevation, slope & aspect colouring for the GLB/3MF preview and export.
Contour lines & GPX routes: Emboss topographic contours at a chosen interval, and import a hike/ride to raise it as a ridge across the terrain.
Frame & engraved label: Add a raised picture-frame border with an embossed place-name and centre coordinates.
3D tree scatter across parks and greenery.
Custom buildings: Draw your own rectangular or polygon footprints that extrude into the model and always print, even with the OSM buildings layer off.
Filament, cost & time estimate shown in the export dialog, plus multi-material 3MF with per-layer colours.
View in AR, a one-click gallery of striking locations, and saved bookmarks.
Multi-tile, grid slice & puzzle pieces with STL, 3MF, and GLB export (single or zipped).

2026-04-15 – v1.9.0 – Planet-Scale OSM Mirror, Railways & Custom Colors

Local Planet OSM Pipeline: Replaced all Overpass API calls with a first-party /osm/ endpoint backed by a full-planet osm2pgsql import (~686M buildings, 260M highways, 62M water, 86M landcover, 30M structures). Fetching is now cache-friendly, rate-limit free, and dramatically faster for dense cities like Boston, NYC, and London. A single config constant lets the frontend fall back to the public Overpass API if the local mirror is ever down.
Railways Layer: New "Railways" toggle alongside Roads and Hiking Trails. Imports active rail types (rail, tram, subway, light rail, monorail, narrow gauge, funicular) and filters out disused/abandoned lines. Fully wired through STL, GLB, and 3MF exports with its own exaggeration slider and URL persistence.
Per-Layer Custom Colors: Every OSM layer (Terrain, Buildings, Water, Roads, Trails, Railways) now has its own color picker inline next to its toggle. Colors persist across reloads via localStorage and flow through to the GLB preview. Defaults match the historical built-in palette so existing models look unchanged until you pick new colors.
True 3MF Multi-Color Output: The 3MF exporter now writes a proper <m:basematerials> resource with one base color per layer, and each object references it via pid/pindex. Slicers like Bambu Studio and PrusaSlicer now open exported 3MF files with every layer pre-assigned its correct color for multi-material printing — previously 3MF files opened as a single gray object.
Bridges Over Water: Roads, trails, and railways tagged bridge=yes are preserved when they cross water (instead of getting clipped) and their deck is anchored to a flat approach-terrain Z instead of sampling the DEM river bed. Bridges now render as seamless continuations of the road network crossing rivers, with printable flat slabs that connect cleanly to the approach roads at both ends.
Roads Never Go Under Water: Non-bridge roads, trails, and railways that cross water polygons are now automatically clipped out of the water bodies using a fast turf-based lineSplit pass, so you never see a highway diving under a river.
Tunnels Hidden: Any way tagged tunnel=yes (roads, trails, or railways) is skipped entirely. Approach roads — which are separate non-tunnel OSM ways — naturally terminate at the portal location, giving a clean entrance/exit appearance without synthesizing portal geometry.
Railway Bridges & Water Clipping: Railways go through the same clipping and bridge-preservation pipeline as roads, so railway bridges over rivers and underground metro lines both look correct out of the box.

2026-04-12 – v1.8.1 – Multi-Mode Flow, AR, and Export UX Fixes

Clear Multi-Mode Readiness: Multi download actions are now hidden until the combined multi model is generated. Added an Awaiting Model Generation state before build completion.
Multi Download Panel Refresh: Updated the multi export panel to match the single-mode style with icon-above-label actions in a clean 4-column row (ZIP, 3MF, STL, GLB), while keeping draggable behavior and tile row/column inputs.
Accurate Tile Status Messaging: Generation status now clearly identifies the active tile in multi mode and computes progress from tile count (Tile X/Y) instead of static stage percentages.
Single-Mode Status Cleanup: Removed unnecessary tile/row/column status text in single mode.
Improved Spinner Behavior: Centered generation overlays over the visible map area (excluding sidebar) and improved immediate spinner feedback for delayed export operations like ZIP/3MF.
Multi-Mode AR Corrections: View in AR now loads the combined multi model (not a single-tile mesh), and AR close behavior now properly clears loading spinners.
Stable Tracking During Multi Builds: Reduced tracking bursts during tile precompute to prevent intermittent analytics endpoint blocking under high-frequency requests.
Map & Texture Limits: Satellite texture zoom is now capped at 16 for consistent texture behavior and improved reliability across larger selections.
Mobile Attribution Positioning: Copyright attribution is now fixed to the bottom-left on mobile.

2026-03-11 – v1.8.0 – High-Resolution Textures & Advanced Terrain Sampling

Streamlined Workflow: Removed all redundant "Apply Changes" buttons from the settings panel. The main "GENERATE" button now dynamically listens to all settings changes and appears automatically when a rebuild is required.
Bilinear Terrain Interpolation: Upgraded the elevation sampler to use bilinear interpolation, providing a smoother and more continuous 3D surface that eliminates staircase artifacts.
Seamless 3D Features: Completely eliminated gaps between roads, trails, buildings, and the terrain by implementing deeper geometry penetration (up to 3.0m real-world depth) and a fully enclosed 6-sided manifold for all linear segments.
Precision Road Following: Increased the subdivision of roads and trails to a 1.0mm model-space maximum segment length, allowing them to follow steep or complex terrain profiles with high fidelity.
Expanded OSM Support: Added support for more road and trail types, including living streets, pedestrian paths, tracks, bridleways, and steps, ensuring a more complete map representation.
Robust Error Handling: Implemented specialized detection for API rate limits (HTTP 429), providing clear instructions to the user if data fetching services are temporarily overloaded.
Hiking Trails Fix: Corrected the positioning and geometry of hiking trails to ensure they are correctly attached to the terrain surface and fixed a bug where the toggle state was not preserved in the URL.

2026-03-01 – Robust Terrain Mesh & Manual Generation

Precision Elevation Pipeline: Switched to WCS 2.0.1 (GeoTIFF) in EPSG:4326 for elevation fetching, replacing unreliable WMS PNG/JPEG. This ensures accurate NoData handling and eliminates invalid terrain facets and spikes at seams.
Smooth Terrain Surfaces: Replaced coarse nearest-neighbor sampling with bilinear interpolation and increased elevation data resolution to eliminate "scan lines" and staircase artifacts at high settings.
Manual "GENERATE" Workflow: Enforced a strict manual generation gate. All settings in the offcanvas (Resolution, Exaggeration, Tiles, Sea Level, etc.) now only update the visual map selection and mark the model as "dirty," requiring a click on the "GENERATE" button to build the 3D model.
Settings Accessibility: Relocated "Boundary Diameter" and "Terrain Resolution" controls to the top of the settings panel so they remain visible regardless of accordion state.
Structural & 3D Printing Fixes: Resolved a long-standing bug where walls were missing on square models. Corrected embossed text orientation: it is now inset (sunken) into the base and readable from the bottom view.
UI Feedback & Stability: Added instant "Combining Generated Tiles..." spinner feedback for large multi-tile sets, fixed a bug where individual multi-tiles would not load in the 3D viewer, prevented map-through clicks on UI elements, ensured the generation modal remains visible after viewing a 3D model, fixed instant map updates when switching between hexagons and squares in Multi-mode, and updated all "View Model" buttons (including on-map tile labels) to consistently use the theme's primary blue color.
Map Labels Toggle: Added a new toggle in the bottom-left to quickly enable or disable street and place name labels on the map.
Google Places Fix: Resolved the "initPlacesAutocomplete is not a function" error by ensuring application logic loads before the Google Maps API.
UI Contextual Controls: Hidden "Circle" and "Custom" shape buttons when in Multi-mode to prevent invalid selection states. Enhanced the "Multi" mode toggle to be always clickable, automatically defaulting to a "Square" shape if an unsupported single-tile shape was active. Fixed a bug where the "GENERATE" button would persist after switching modes even if no shape was present on the map.

2026-02-28 – Copernicus Dataset & Texture Seamlessness

Copernicus DEM Switch: Fully transitioned to the high-resolution Copernicus GLO-30 dataset. This provides significantly more accurate elevation data globally—say goodbye to the holes and missing data issues common with ASTER!
Seamless Satellite Textures: Fixed a terrain classification bug where polygon facets on steep slopes would "poke through" the satellite texture. Textures now map perfectly to the top surface regardless of the terrain's incline.
Improved Mesh Generation: Enhanced internal tagging of terrain facets (top, bottom, walls) for more reliable material application in GLB and 3MF exports.

2026-02-27 – Custom Shape Clipping & Orientation Fixes

Universal Shape Clipping: OSM data (buildings, roads, water, trails) and scattered trees are now strictly and accurately clipped to the boundaries of ALL shapes (Square, Circle, Hexagon, and Custom). Improved clipping robustness for MultiPolygons and complex line intersections by utilizing high-precision LineString-to-Polygon intersection logic.
Missing Features Fix: Fixed a bug that caused roads, trails, trees, and embossed text to be missing from certain exported models (STL).
3D Viewer & Custom Shape Fix: Standardized on a right-handed coordinate system (North = +Y) to fully resolve the "flipped" appearance of custom shapes. The 3D viewer now defaults to a South-facing camera looking North for a natural map-like orientation.
Area Limit: All shapes, including circles and custom polygons, are now limited to a maximum area of 120km x 120km (14,400 km²) to ensure performance and model quality.
SweetAlert2 Integration: Replaced all native browser alerts and prompts with modern, theme-consistent SweetAlert2 modals for a smoother and more professional user experience.
Custom Shape Support: Introduced "Custom" shape mode powered by Leaflet-Geoman. You can now draw Polygons, Rectangles, and Circles (which auto-convert to polygons for easy editing) directly on the map.
Precision Texture Mapping: Satellite imagery is now strictly applied only to the top terrain surface of GLB models. It now always uses high-detail zoom 18 for the best possible quality across all models, with automatic downscaling for large areas to maintain performance.
Automatic Workflow: The model generation modal now automatically appears after drawing a custom shape or selecting a standard shape (Square, Circle, Hexagon), streamlining the export process.
Reliable Geoman Toolbar: Optimized the drawing tools to ensure they are always visible and correctly oriented in a vertical column when in Custom mode.
Elevation Data: Switched back to the reliable ASTER 30m dataset to ensure consistent performance while we finalize local Copernicus DEM support.
Progress & Readability: Removed progress bars in favor of cleaner status updates and enhanced UI readability with text shadows across map controls.

2026-02-27 – Usage Statistics & Global Activity Map

Interactive Stats Modal: Added a comprehensive "Stats" dashboard featuring Chart.js visualizations for daily activity, models generated, export formats, modes (Single vs Multi), and shapes.
Global Model Generation Activity: Implemented a "sexy" dark-themed global map visualizing real-time and historical model generation events.
Temporal Animation & Slider: Added a time slider and play/pause controls to the global map, allowing users to watch the growth of TerraPrinter usage across the world over time.
Map Fullscreen Support: Integrated a dedicated fullscreen button for the activity map, ensuring time controls remain accessible for a focused visualization experience.
Refined Visuals: Optimized map markers to a clean "pixel-sized" turquoise look and blended the map background with the site's dark theme for better aesthetic consistency.
Improved Feedback: Replaced the static "Generating..." text with a dynamic progress bar and descriptive status updates during model generation and export.
Terminological Update: Renamed "Events" to "Models Generated" throughout the statistics interface for improved clarity.

2026-02-21 – Multi overlay, satellite texture, and multi‑tile stability

Floating Multi overlay: When Multi mode is active, Rows/Columns and Multi actions now appear in a small floating overlay on the map. They return to the panel in Single mode.
No map interference: Clicks, touches, scrolls, and drags on the overlay no longer trigger map panning/zooming beneath it.
Mobile friendly: The overlay is collapsible and draggable (constrained within the map) so it won’t block content on small screens.
Satellite texture parity: Preview texture now uses the currently visible basemap and zoom, stitches all needed tiles to cover the entire selection (including hexagons), and renders in the correct sRGB color space for brightness that matches the map.
Unlit material for fidelity: Terrain preview with satellite texture uses an unlit material (no tone mapping) for a near 1:1 visual match with Leaflet.
Multi‑tile export stability: Fixed a “Maximum call stack size exceeded” error when aggregating large facet arrays by appending in a safe loop instead of using spread arguments.

2026-02-14 – UI/UX Workflow & Control Refinement

Bottom Control Bar: Moved the Mode and Shape selection buttons to the bottom of the map to prevent overlap with search and settings on mobile.
Radio-Style Controls: Mode (Single/Multi) and Shape buttons now behave like strict radio buttons, ensuring clear visual state.
Smart Panel Management: The settings panel now automatically hides when the download/view modal is shown, keeping the workspace clean.
Restored Modal Triggers: Ensured the download modal correctly pops up after map clicks or major setting applications.
Z-Index & Interaction Fixes: Improved reliability of modal backdrops and offcanvas interactions on mobile.

2026-02-13 – UX Refinement & AR Finalization

Compact UI Layout: Unified Mode and Shape selection into a single, smaller top bar for better visibility on all screens.
Smart Modal Logic: Prevents automatic pop-ups when switching shapes and ensures background backdrops are always properly cleared.
Definitive AR Mounting: Finalized the Z-up native export and orientation logic so models mount perfectly flush against walls (Art mode) and sit flat on floors.
Mobile Combined View: Fixed the "View Combined Model" feature for mobile devices, ensuring all layers (trails, trees) are correctly aggregated.
Map Interaction Fixes: Prevented UI button clicks from triggering map events and resolved shape-switching script errors.

2026-02-13 – Advanced Personalization & Hexagonal Tiling

Hexagonal & Circular Bases: Added support for non-rectangular shapes, perfect for "Terrain Coins" and hexagonal gaming tiles.
Smooth Wall Edges: New high-resolution clipping algorithm for perfectly smooth vertical sides on circular and hexagonal models.
Hexagonal Multi-Tile Mode: Generate large-scale staggered honeycomb grids that fit together seamlessly.
Combined Model Export: Stitch multiple tiles into a single seamless GLB, STL, or multi-material 3MF file.
3D Text Embossing: Add custom labels and location names directly to the base of your 3D models.
Satellite Texture Overlay: Preview realistic terrain in the 3D viewer with satellite imagery.
Advanced Layers: Integrated hiking trails from OSM and experimental tree scatter for enhanced architectural detail.
Geometry Optimization: Added Laplacian smoothing to reduce artifacts and high-resolution clipping with bilinear elevation interpolation.
Saved Locations: Bookmark and return to your favorite geographic coordinates and settings.
AR Preview: View your models in Augmented Reality with support for Floor and Wall (Art) placement modes. Corrected wall orientation to ensure models mount flat by their base.
Centered 3D Viewer: Natively centered GLB export for stable rotation and consistent AR placement.

2026-02-13 – STL Export & UI Enhancements

Added "Download STL" option for single-tile and combined models
