Pick a region on the map and click Generate STL. The browser fetches Swiss elevation data (SwissAltiRegio 10 m, © swisstopo) directly and builds a 3D-printable terrain model — no server required.
Z-scale is the vertical-to-horizontal exaggeration ratio: 1 = true 1:1 proportions (1 m horizontal = 1 m vertical at the model's scale), 2 = heights doubled, and so on. Auto picks a natural-looking value that aims for ~15 % of the print size in vertical relief, never below true scale and capped at 5×.
Tiling: set Tile cols and Tile rows in Advanced options to split any shape into a grid of adjacent tiles. Or import a GeoJSON / KML file containing multiple polygons — each polygon becomes its own tile. The largest tile prints at the chosen Print size; every other tile is proportionally smaller at the same XY scale, with its own auto-fitted textplate and north arrow (reverse-geocoded from the tile's own centre). All tiles share the same Z scale, so they line up at every seam in both XY and height.
