the magic cup

The magic cup works on the same principle as the Pythagorean cup, except that the water stays in the walls of the cup.
Try printing without supports, so as not to block the circuit and make sure that the vents are open.
For useful emptying of the outer hole on the cup.
Load the cup up to the level to have water in the cup. Exceed the level and the water starts to disappear.
I haven't tested the model yet, but I will come back with a functionality test.
