3-layer Gimbal Die

grabcad

Here's a Die that is enclosed by 3 gimbals. This die can be thrown around and the rotational inertia of the throw would cause the gimbals (each being 30 or 60 off axis) to rotate which would result in the die rotating. In order to allow the die to always have a flat face pointing up, just like a regular die, a counter weight is placed inside the die. This counter weight is a sphere (shaped in a form of a monster eye ball) that can freely move around in an opening inside the die to lower the center of mass of a particular face (see the sectionview posted). Also for fun I modeled the die with a monster on the inside where you can see his eye throw the middle hole on each side of the cube and the other numbers looks like it's punching from the inside trying to get out cause. Also I know that the cracks on each face might not show up in the final model because of the printers resolution limitation but they are cracks. They definitely don't need to be perfect and maybe that would add a little bit of randomness to it :)
