I printed one of the propellers just to see how it would come out and it was so nice I printed two more and designed some more parts to turn it into a backyard wind spinner decoration.

Uses a couple 3mm stainless steel rods and the attached parts. Use original designs blades … they are so nice! 

Printed in PETG to hold up to Sun. The little shim is to keep propeller mount from moving forward/backward on shaft. It'll be pretty tight to put on (maybe warm up?). I didn't use any lubrication yet, but I did put a bit of E6000 glue to secure 3mm shaft to the “h-v joint” (just horizontal shaft, vertical you want to be able to pivot)
