"Tradition says Pythagoras, during water supply works in Samos around 530 BC moderated the workers' wine drinking by inventing the 'fair cup'. When the wine surpasses the line, the cup totally empties, so the greedy one is punished."
Now you don't have to go to the island of Samos to get one! Print one now!
The STL will print a cup arround 3cm high, so you may want to scale it a bit. A scale of 1.5 will render a 5cm (2in) cup, and so on.
