Pythagorean cup

prusaprinters

<p>A pythagorean cup is similar to a regular cup, with the exception that if you fill above a certain height inside the cup, then all of the contents of the cup will be emptied.</p> <p>This is good to teach people not to be greedy ;)</p> <p>It works by having a hole at the bottom of the cup, that goes up through the center part of the cup and back down to inside the cup. Once the liquid passes a certain point, gravity pulls the liquid out and the concept of "Communicating Vessels" makes sure to empty the whole cup out.</p> <p>You can read more about this cup here: <a href="https://en.wikipedia.org/wiki/Pythagorean_cup">https://en.wikipedia.org/wiki/Pythagorean_cup</a></p> <p>I ran into this randomly one day and thought it would be a nice project to create with my printer.</p> <p>I modelled it in Fusion360. There are two versions of it, one with a handle and one without. Since I wasn't going to actually use it, I printed the version without the handle for simplicity, but I added a nice coffee-mug-like handle. If you print the version with the handle you'll probably need supports.<br/> The version I printed without the handle works just as described. The version with the handle is the same exact model, so should work too.</p> <p>NOTE: I do not recommend actually drinking from the cup, unless you know the material you printed it from is clean and safe for drinking out of!</p> <h3>Print instructions</h3><p>I printed this with PLA (from Hatchbox) with 0.2mm layer height.<br/> Took about 8 hours and works nicely.</p> <p>The version without the handle doesn't need any supports.<br/> If you want to print the handle, you might need to add supports under the handle.</p>
