Two colours without an AMS: swap filament by height, not by feature. The model has 4 mm of base under 2,000 m, and every 100 m of mountain adds 2.14 mm. Swap at 42.6 mm and everything above 3,800 m prints white, a snow-capped summit from one colour change.The Matterhorn is the mountain everybody draws when they're asked to draw a mountain, so it seemed like the right one to print first.
This is a 7 km square centred on the summit, on the Swiss–Italian border between Zermatt and Breuil-Cervinia. At 150 mm across that works out to 1:46,667, and the terrain stands about 50 mm tall with no vertical exaggeration at all. The mountain is steep enough on its own. Push it to 2x and it turns into a spike that looks fake and prints badly.
What's on it
Terrain from 2,000 m up to the peak
Contour lines raised 0.6 mm, one every 100 m of real height. They do most of the work on a single-colour print, catching the light so the ridges read from across a room.
Lakes and streams cut into the surface rather than sitting on top, so the water sits in a channel you can feel with a fingernail
One honest note: the elevation data tops out at about 4,340 m, while the real summit is 4,478 m. Global terrain data is gridded at roughly 20–30 m, and a summit as sharp as this one gets averaged with the slopes around it. The shape is right; the last hundred metres of needle are softened.
Files
matterhorn-150mm.stl: everything merged, for any printer, single colour
matterhorn-150mm.3mf: terrain, contour lines, lakes and rivers as separate parts with colours assigned. Opens ready to go in Bambu Studio, OrcaSlicer and PrusaSlicer.
Print settings that worked
0.16–0.2 mm layers. Terrain is all gentle slopes, which is exactly where layer lines show.
No supports. It's a heightfield; nothing overhangs.
2–3 walls, 10–15 % infill
Matte PLA if you have it. A matte grey Matterhorn looks like a museum piece; glossy shows every layer.

Make it bigger, smaller or somewhere else
I made this with MapsTo3D, a free browser tool I built: no account, no install, nothing uploaded. If you want the Matterhorn with Zermatt included, a round version for a coaster, or your own local hill, frame the area and export. It takes about a minute. The same tool does buildings, roads, GPX routes and tiling for maps bigger than your bed.
