Simple 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.

Matt made a version for 3D printers. You can find it here: http://www.thingiverse.com/thing:620
