How this model is made
1
Capture
Mapped building outlines are read from OpenStreetMap and the ground beneath them sampled from open terrain tiles.
2
Solidify
The surface is closed into a watertight solid with a plinth and a raised rim, sharing boundary vertices so there are no seams for a slicer to complain about.
3Print
Download the STL and slice it. No supports needed: overhangs are removed by construction, and anything too fine for a nozzle is dropped rather than printed badly.
