This is a simple model designed to demonstrate the Pythagorean theorem using liquid. For best results, print it with transparent filament.

Once printed, carefully glue the two parts together to make it watertight. The model has two holes for filling it with liquid — seal them using M3 bolts wrapped with a bit of tape.

Tip: Don’t leave liquid inside for too long — about 2 hours max — as the plastic might start to absorb it or leak.
