Pythagorean Cup.
Goals
The Pythagorean Cup is a classic practical joke invented by Pythagoras himself, in which a patron who fills his glass too full (traditionally with wine), will have all of his drink drained from his glass (and onto his clothes)
Design an easily printed Pythagorean cup
Contributions
In this design, the volume of the glass holds one drink of wine (5 oz) before draining, allowing one to keep track of their consumption
In addition, it is designed to be easily printed and assembled, as it does not require interior support and has been toleranced for most commercial FDM printers
Results
A great example of siphoning, and a fun practical joke
