Air Vane Motor
After seeing some kids playing with a little air plane powered by compressed air from a soda bottle, I decided to see if I could make a laser cuttable version of such a motor.
This is not a very powerful or efficient motor, but it is a fully working printable ("cuttable"?) air vane motor. My next goal will be to make a full printable bottle-powered park-flyer.
