Jazzy's BB Top

Spins for over one minute! Just print, finish, pop a BB in the socket, and spin away! These can not be scaled! One file uses an Airsoft BB (6mm) and the other uses a .177 caliber (4.5mm) BB. They seem to spin equally well but I think the metal one is slightly better.

WARNING: Not for children under 3 years of age! The BB could detach from the toy and present a choking hazard!
