About this 3D model
I made this from a picture -> svg -> thinkercad Mi original design had the wheel holes, but it made a mess with infill because they were to small. My original idea was to make this a customizable think, but Tinkercad has better lloking fonts to make keychains, so do it there if you like. Edit: https://tinkercad.com/things/3tYeZC58AHs
