windmill rev extrusion
thingiverse
a windmill-ish thing made to capture wind and maybe spin a motor if attatched to the back rod (remove back cone). print 11 blades, that slide into hub (might need sanding) put a ball bearing into the base rod 2 and put glue axle inside cone. push rod through top rod and insert back counterweight through the back. slide in dovetail connection of base rod 1 and then use a ~2 cm long machine screw threw base and into base rod 1 (needs threading). then slide the base onto a 1 inch rev extrusion. made for class project, took 2 weeks in-class, remix the axle for different bearing sizes if you want.
