Nice design! However, in my slicer I see a few problems that degrade the printing performance. I would love to offer a few suggestions to further improve the design :) First of all, I don't mind you putting a trademark on it, but when you place it where the printer has to make a bridge, it will cause problems with that bridge.

Secondly, for the Large version of the half-wheel, the flat part stops a bit short of the center, causing a strange gap.
