Hollow d20 for various shenanigans

thingiverse

A simple d20 design I did, with a little twist: it has a big cavity inside. (two variants) You can fill it mid printing with beads, powder, water (or liquid metal in my case) You can also leave it empty and have a decent lightweight d20. Its center of mass is within printer precision to the geometric midpoint. 25 mm diameter, 20 mm across faces. Support not needed, print it resting on its "one" face. It was designed for 0.25 mm nozzles. Slice 0.1 mm for best results.
