Make 3D printable maps from your AI assistant
Ask Claude, ChatGPT or any other assistant for “a 3D printable model of Mount Fuji” and get a link that opens TerraPrinter and builds the model for you — ready to download as STL, 3MF, GLB or OBJ.
Claude — add the connector
https://terraprinter.com/mcp - In Claude, open Settings → Connectors and choose Add custom connector.
- Name it TerraPrinter, paste the URL above, and save. No sign-in needed.
- In a chat, enable TerraPrinter from the tools menu and ask: “Make me a 3D printable model of the Matterhorn.”
Works in Claude Desktop, claude.ai and Claude Code (claude mcp add --transport http terraprinter https://terraprinter.com/mcp) — and in any other MCP client that supports remote servers (Cursor, VS Code, LibreChat…).
ChatGPT — connector or Custom GPT
As a connector (ChatGPT Plus/Pro/Business with developer mode):
- Settings → Apps & Connectors → Advanced settings, turn on Developer mode.
- Create a connector, paste
https://terraprinter.com/mcp, authentication None.
As a Custom GPT:
- Create a GPT → Configure → Actions → Create new action.
- Import from URL:
https://terraprinter.com/openapi.json, authentication None. - Instructions, for example: “When the user wants a 3D print, map or model of a place, call createModel and give them the model_url.”
Any assistant — plain links
No setup needed: assistants that read llms.txt can link straight to a model. Opening one of these builds it automatically:

- https://terraprinter.com/make?lat=40.7484&lon=-73.9857&km=3&shape=square
- https://terraprinter.com/make?place=Olympus+Mons&world=mars
place | Place name — or give lat and lon instead. |
world | earth (default), mars, moon, mercury, venus, pluto, charon, ceres or vesta. |
km | Width of the area in km. Up to 120 on Earth, 3000 on Venus, 2000 on Mars, 1500 on Mercury, 1000 on the Moon and Pluto, 500 on Charon and Ceres, 400 on Vesta. Default: chosen from the place. |
shape | circle, square, rect or hexagon. |
layers | Comma list of buildings,water,roads,trails,rail,parks, or none for bare terrain. |
size_mm | Printed width in mm (default 200). |
vertical_exaggeration | Height multiplier (default 1.5). |
base_mm | Base thickness in mm (default 5). |
Add format=json (or call /make/link) to get the links as JSON instead of a redirect; /make/search?q=… lists matching places.
Models are generated in your browser from Copernicus DEM elevation and OpenStreetMap data; place names come from OpenStreetMap Nominatim and the IAU planetary gazetteer. TerraPrinter only receives the place and settings your assistant sends, never the conversation; place searches are cached to spare the geocoder. See the privacy policy.
