TerrainMaker - Design Multicolor 3D Maps!

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 FeaturesCustom 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 detailUtility 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 model
