3D print a GPX route: from Strava track to terrain model

Step-by-step: from GPX file to printed route

Five steps. If the GPX is already on your disk, the modeling part takes about ten minutes.

1. 1. Export the GPX from Strava, Garmin Connect or Komoot

   Every mainstream tracking app can hand you a GPX file of a recorded activity or a planned route:

   • Strava: open the activity on the website and choose Export GPX from the activity menu. Planned routes have the same export on the route page.
   • Garmin Connect: open the activity, click the gear icon and choose Export to GPX.
   • Komoot: open the tour and use the GPX download in the tour menu.

   If the print is a gift, ask for the file: a GPX is tiny and survives any messenger. One race, one .gpx, that's all you need.

2. 2. Select the area around the route

   Open the editor and draw a selection that covers the whole track with a little margin. The crop decides the story: a tight selection around the summit day makes the route large and dramatic, a wide selection shows the whole trek but shrinks the line. For a point-to-point course like a marathon, match the selection's aspect ratio to the route so you don't spend bed space on empty terrain.

   City races benefit from keeping OpenStreetMap buildings, roads and water in the model, so the runner can find their street. Alpine and long-distance routes usually read better as pure terrain, which also scales to much larger selections than a building-dense city does.

3. 3. Upload the GPX in the Addons tab

   Switch to the Addonstab and upload the file under GPX Route. The track is embossed onto the terrain as a raised line that follows every switchback, and it stays its own colored part all the way into the export. You control the route's width and height in millimeters: for a palm-sized print, a width around 1.5 to 2 mm keeps the line crisp without swallowing detail; go wider when the route is the hero of a large model.

   You can add several GPX files to one model. A five-day trek or a season of training rides embosses just as cleanly as a single race.

4. 4. Tune the terrain, then the frame

   Hit Generate and orbit the preview. For mountain routes, check the vertical exaggeration in the Topography tab: after a generation Map2Model knows the real relief of your area and suggests a factor that keeps the mountains readable at print size. Gentle hills often want 2x or more, while dramatic alpine terrain can stay near 1x. The route follows the terrain, so the exaggeration makes every climb in the track visible too.

   Then make it a keepsake. Color the terrain with elevation bands for a classic topo look or drape satellite imagery over it. Add a frame and engrave text into it: the race name, the date, a finishing time. The frame also offers an opt-in embossed scale bar and north arrow, which turn a nice print into something that reads like a real map.

5. 5. Export, slice and print

   Export the multicolor 3MF. Terrain, route, frame and any map features are separate parts with their own colors, so Bambu Studio and OrcaSlicer map each one to an AMS slot, and PrusaSlicer treats them as objects you can assign to MMU extruders. Give the route a strongly contrasting filament: a red or orange line on neutral terrain is readable from across the room. If you only need one solid body, export the merged STL instead; the route still stands raised on the surface.

Tips for a great route print

Print settings for terrain relief

Terrain rewards fine layers: 0.12 to 0.16 mm makes contours flow instead of stair-stepping, and the raised route stays sharp. Infill of 10 to 15 percent is plenty for a display piece, supports are unnecessary for terrain, and a 2 to 4 mm base keeps a bed-filling model rigid and warp-free.

Choose the route filament first

The line is thin, so contrast does the work. High-visibility colors, silk filaments or a glow-in-the-dark route over matte terrain all photograph well. Keep the terrain palette calm so the track stays the focal point.

Make the gift specific

The difference between a nice print and a gift someone keeps on their desk is specificity: their exact course, their race name and finishing date engraved in the frame, the scale bar showing how far they actually went. Personal prints and gifts are always fine; if you want to sell route models, see the commercial use page first.
