About this 3D model

A spinning top (fighting spintop) that competes with the overly expensive Beyblades. Made by Boris (9 years old) on a RepRap at the TU Delft. It will fight other Beyblades and win. You still have to bring your own launcher (either with a ripcord or motorized).Let it rip!http://www.youtube.com/watch?v=bPoYmsNnrwI
