This was my first 3D model using Fusion360. It was done to learn the Fusion interface as well as be an interesting model to display.
Unlike other pythagoras cups, the inlet tube is hidden on the side of the cup instead of in the center. This makes it a little easier to surprise greedy, unsuspecting users. It works best when held perpendicular to the ground and is filled fairly quickly. Depending on the size you print at, water may need to be removed from tube between uses (water droplets can trap air inhibiting function of the tube). Other than that, it has performed well.
The function of this cup depends on the tube being completely airtight, so I recommend using 4+ perimeter shells and making sure the seam starts randomly on each one. A high flow rate is also essential. I printed without supports and only had some minor drooping; it just depends on your printer's overhang capabilities.
