Actual airfoil equipped propeller. What is more fun than to play outdoors with your own printed things! Indoor is also possible. The airfoils used is simillar to these: http://m-selig.ae.illinois.edu/ads/coord_database.html
As a bonus a spool with hole in it for the cord, but located at the BOTTOM = non breaking.
Have a look here for other components for the handle: http://www.thingiverse.com/thing:51489
PS: please wear safety goggles, etc. In case it breaks can be dangerous as PLA shrapnel.
