3dsets Model 9/10 Motor Fan

thingiverse

Fan that slides onto the motor shaft. Standard is for 5mm shafts as my Lindinger Planet Hobby 3530, but I have included an untested version for 4mm shafts too. It is very tight, so you maybe have to use a file or a drill. I didn't want to make it loose, so this is intentional. use M3 grubscrew to tighten I have used a (it seems now defunct) openscad turbine generator for the fan and added a shroud and m3 grubscrew hole you can find the car on https://www.3dsets.com
