Greedy Bath Cup

Teach children about fluids in the bath. The Greedy Cup Siphon, properly called the Pythagorean cup works on the same principal as a modern toilet bowl. When the water level in the bowl rises high enough, a siphon is created, emptying the bowl.

The channels in this cup are hidden in the walls, so it appears to be a normal cup at first glance.

Printing

Print at full size with .4 or .6 nozzle. The channels may be too small to work reliably if scaled down.

Do not use supports.

Drinking from 3d printed plastic is not recommended.
