Magnetic drone race track planner with filament

Inspired by other similar track planners, but I modelled a filament holder for TPU. This way, the track layout is clearer, and you can stack the gates using magnets.

Print in PLA, use 2x6mm neodymium magnets, maybe use a vice or pliers to get them in. If the magnet holes have sagging because it's an overhang, use a knife to just make it smooth so the magnet fits in.

Just make sure all the magnets point in the same direction (when standing upright) so that different pieces stick correctly. The one magnet underneath the arch of the stackable gate should be the opposite of all others, this way the filament holder can stick upside down if you need it to.
