GPX Track Overlay

Generate a 3D-printable STL file from your GPX activity track (running, cycling, hiking, etc.). The track will be scaled and clipped to match Castelló de la Plana so you can add it as a colored overlay in your slicer. You can also use this tool without a miniature to generate a standalone track STL. Step-by-step guide
