About this 3D model

For a little fun, I thought I would share this small pile of hockey pucks. It took 5 attempts, but I got something that seems to work. Do not give up, it will (eventually work) I needed to set the tolerance in the SCAD file to 0.5, and I printed it with a 0.35 J head on a Prusa Printer. Sliced with Slic3r 0.98 .25 layer
