About this route in 3D
Open the designer and the real GR 42 becomes a solid topographic model: the route rides on top of true elevation terrain, surrounding peaks and valleys included, with automatic place labels for the towns and landmarks along the way.
Everything is editable. Swap in your own dates, rename the labels, change the base shape, or replace the route entirely with the trip YOU took. The model you see is the model you get, as a watertight file ready for any 3D printer, or as a finished print made by us.
How it works
- Open the GR 42 in our 3D designer. Real terrain, real elevation, in your browser.
- Make it yours: use your own route, dates, labels, size and shape.
- Download the printable STL file, or order a finished 3D print. We ship to 50 countries, with optional wood frame and LED base.
Common questions
- Is this the real terrain of the GR 42?
- Yes. The 3D model is built from real elevation data, so every climb, ridge and valley along the GR 42 appears at true relative height.
- Can I use my own route instead?
- Yes. The designer accepts your Google Timeline export, geo-tagged photos, or a route you draw by hand. The GR 42 is just the starting point.
- How do I get the finished model?
- Two ways: download a printable STL or GLB file for your own 3D printer, or order a finished print and we make it and ship it. We deliver to 50 countries, with optional wood frame and LED base.
- Can I download the GR 42 as an STL file for my own 3D printer?
- Yes. The printable STL (or GLB) file of the GR 42 costs $10, one token, and is watertight and ready to slice. You can also change the size, base shape and labels before you export it.
