Spinning Top - Dridel

A great toy, one small part, just print and spin. low-cost to print because of the small size. Design is based on a bicycle wheel, which gives great balance with low weight. Can spin for more than one minute, with amazing stability. Two versions attached: one is plain, the other comes with Hebrew letters like in a Dreidel (http://en.wikipedia.org/wiki/Dreidel). Rhino and Stl files attached.
