Gravitrax compatible Inserts

Some custom-made inserts made from scratch compatible to Gravitrax basic tiles such as https://www.thingiverse.com/thing:3552100. The inserts are designed to have a small "chamfer" (0.5mm) on the bottom to prevent "elephant's foot". Some of the inserts can be mirrored on your slicer.

New inserts are going to be published soon and I also have to change the F3D file. If that happens, I want you to delete the old F3D file if you have already downloaded it earlier and download the new F3D file I have published recently.
