Terrain2STL

What is Terrain2STL?

Terrain2STL is one of the oldest and simplest ways to turn a real landscape into a printable file. You move a rectangular selection box over a map, set its width and height, and the site builds an STL of the ground inside it using the SRTM elevation survey from 2000.

The settings are short and easy to follow: box width, height and rotation, a vertical scale factor to make hills stand out, a base thickness in millimeters, and a water drop option that lowers the sea so coastlines read clearly. There is no sign-up and no fee, and the project is supported by donations.

The trade-off is detail. The source data has roughly 90 metre resolution, so it shines on mountains, islands and valleys, while small hills and city-scale features come out soft. It suits anyone who wants a quick single-color relief print of a favorite peak without learning GIS software.

What you can make

• Mountain relief tiles
• Island and coastline models
• Valley and canyon terrain
• Topographic desk pieces

How to use Terrain2STL

1. Open the map and move the selection box to your area
2. Set box width and height, vertical scale and base height
3. Click to create the STL and download it
4. Slice and print
