Washing Machine Motor 2Piece Bolt on Cooling Fan 15mm Axis

Made this fan for my electric motorcycle project that uses a universal brushed washing machine motor with multiple stages of gearing for the uphill torque.
Many thanks to RENNAT who published the openSCAD source that I used to make this!

This is not yet tested in longer operation and considering these motors can spin more than 12000 rpm (measured without load) I have no idea if this will be strong enough to stay on with the 2 pcs. M3x20 screws that are so far considered...
I printed this in PETG and everything except the thin ends of the fan appears quite sturdy!
Anyhow OpenSCAD source is included so do mix it up!

The geardown process also involves this design: https://www.thingiverse.com/thing:3699829 check it out!
