Monostatic Body

I received the 3D print of the one-sided die that I designed. Unfortunately it sometimes gets stuck upside-down on the unstable equilibrium. I have designed a new version which I think should fix the problem: http://www.shapeways.com/model/979729/monostatic-body.html. This version has a ridge on top which should make the unstable equilibrium... less stable:


The ridge causes the center of mass to raise a bit (to 0.9mm below the cylinder's center). I feel confident that this version of the shape should work - it will take about two weeks until I get the printed copy from Shapeways.
