Pythagoras Cup 3D print model

This is a model of Pythagorean cup. It includes two parts; one single full-version part, and also half of the model to show and understand how it works. Can glue the half with plexiglass and see it in action as well. The original model is about 17cm long, but you can scale it to any size you want. P.S: I printed it myself with %65 scale and it works.
