Ork Copter rotor

A friend of mine who plays Orks in warhammer 40K asked me to print some copter rotors for some pieces he was making. So I found the kilacopter model and grabbed the rotor. But they were not flat and didn't print usable rotors easily. So I laboriously de-tilted each rotor blade and rebuilt the rotor assembly in tinkecad. They worked well for his models, Examples of these are shown above. So I am publishing them. Enjoy!

I printed in PLA, 0.2mm layers, no supports or rafts. Be careful getting these off the build plate. Though the blades superglue onto the central shaft pretty well if you break off a blade.

Magnets glued onto the bottom of the rotor and mounting location (opposite poles facing each other so they attract) on the vehicle allow you tp remove rotors, permitting transport without damaging rotors. This is a nice feature to include and it is recommended. See photo.
