TerrainMaker.com, a web based tool to generate 3D printable terrain models from anywhere in the world. As of April 3 2026, I am about 400 hours into this project!

Main Features

• Custom Base Shapes (via SVG upload, draw on map, island capture. This allows for custom inlays, puzzles, grids, etc.)
  • This is the latest major update and it poked every corner of the app, there will be some bugs.
• Feature Editor - Find features, rivers etc. then edit their path (eg adjust a river that is misaligned to the topography data)
• Draw Features (draw splines, like a hike route directly on the map! also polygons and negative polygons)
• COASTER MODE - fun little mode that lets you flatten the terrain and print coasters with elevation layers and features (bike route) essentially as a flat image with a little border detail
• Utility Options - this allows you to add holes to the back of your models for mounting.
• Feature Painter: Find and add Trails, Water features, Glaciers, Roads, upload a GPX file, etc.
• Slice your models horizontally: to create "elevation layers" (Multicolor Printing)
• Global Data: It pulls high-res terrain data
• 3D Print Ready: It doesn't just give you a raw surface; it generates solid, watertight meshes with bases and walls automatically.
• Browser Based: No software to install.
