Print the mountain you climbed
Upload your GPX files from a hike or climb. TrekForge creates two STL files ready to be 3D-printed: the terrain, and your route as an inlay.
Selected files
Nothing is uploaded until you continue.
How it works
- Upload your GPX files.
- TrekForge downloads elevation data.
- Tune the model in a live 3D preview.
- Download the STL files, slice them and print.
What you need
- A GPX file from a watch, a phone, or an app like WorkOutDoors, Strava, Garmin Connect or Komoot.
- A free OpenTopography API key.
- Any filament printer. One colour at a time is enough: print the terrain, swap the spool, print the route.
- A slicer such as PrusaSlicer or Cura.
Good for
- Summit days.
- Multi-day treks, one file per day.
- Long-distance paths, trail races and bike tours.
- A gift for whoever walked it with you.
Flat routes need more vertical exaggeration to show any shape.
Why I built it
I started with long-distance walking: the Nijmegen Marches, 100 km in 24 hours, a walk to every Wetherspoons in Kent, and Dartmoor in a straight line.
More recently I've been adding some height. So far that means Toubkal, the highest mountain in Morocco; Korab, the highest in both Albania and North Macedonia; and Teide, the highest in Spain. Kilimanjaro is next year.
After each trip I wanted something to keep: the mountain on my desk, with the route I actually walked picked out in a second colour. So I made TrekForge.
The examples below are my own tracks from those climbs.
