About this 3D model

I was inspired by the puck from fflood http://www.thingiverse.com/thing:39864 but wanted something that could print with minimal supports so I took the concept and redesigned one from scratch based on a puck that I have. Enjoy! Update: Even at 85% fill this puck is slightly lighter weight than another I have. It is also rather 'bouncy' and likes to catch the edge and roll. The material held up well to an hour or so of play with only a couple of the runners busting.
