Finger Engine Treadle Fan

cults3d

I had always been kinda fascinated with how antique sewing machines worked. Foot powered treadles. Saw some finger engines made by machinists in the past and figured I'd try my hand at making such a thing. My intent was to make a fan to blow air. Well it doesn't really turn fast enough to generate any appreciable wind. But is still a fun desktop toy! The lever.stl requires supports. You'll need some 5-6mm rods and some glue. I'm partial to gorilla glue as it expands and that makes for a snug fit.
