White strong and flexible print on a quarter.
Six sided die with ball bearings (1-6) on each side. With a .25mm clearance around the balls they should all move freely. Slightly smaller version, by request, but I couldn't make it much smaller without getting a little too close to the minimum space needed for moving parts. They're wedged in there pretty tight so you'll need to take some time and break them loose.
