Open RC F1 Non slip pinion gear

thingiverse

This is a pinion gear that takes an m3 nut into the provided slot so that you can use an m3 screw to fasten the gear to the motor shaft. I saw some people complain that the pinion gear slipped off and I also experienced the slippage. This gear does not slip anymore. The current hole is about 2mm but I usually drill it a little bigger if needed. Printing at 100% infill ensures that the design and gear is not compromised when increasing the hole size.
