Pythagorean cup
thingiverse
This is a variation of a Pythagorean cup that looks like a regular cup. If the cup is not completely filled, the liquid does not pour out if you hold the cup straight, but when filling above a certain level, all the liquid will drain to the bottom. You need to print with custom supports.
