If the cup is partially filled, it holds liquid which can be drunk in the usual fashion. If it is overfilled it drains the entire contents of the cup into the drinker's lap. This object was classically used as a warning of the dangers of gluttony and over-consumption.  \u003c\/p\u003e\u003cp\u003eUnfortunately, Pythagorean cups feature a distinctive central stem to house the siphon tube which drains the cup - see for instance \u003ca target=\"_blank\" rel=\"noopener noreferrer ugc\" href=\"https:\/\/www.printables.com\/model\/669646-classic-pythagorean-greedy-syphon-cup\"\u003ehttps:\/\/www.printables.com\/model\/669646-classic-pythagorean-greedy-syphon-cup\u003c\/a\u003e. This gives away the surprise and spoils some of the fun! Fortunately, modern 3D printing allows us to build a more devious cup, with a hidden siphon.  \u003c\/p\u003e\u003cp\u003eThis object is a Pythagorean cup with the siphon tube concealed in the drinking vessel walls. The siphon tube traverses more than 300 degrees of the circumference of the rim, so a moderately filled cup will not drain when it is tilted. This object has been printed and tested, and is 100% functional! It makes a great brainteaser or science demonstration for students.\u003c\/p\u003e\u003cp\u003eOne good way to help understand the object is through this educational video.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eInstructions\u003cbr\u003eThis object was originally printed on a Makerbot Replicator 2:  \u003c\/p\u003e\u003cp\u003e\u003cbr\u003eMaterial: Makerbot True Yellow PLA (Or your own favorite choice)\u003c\/p\u003e\u003cp\u003eLayer Thickness: 0.2 mm\u003c\/p\u003e\u003cp\u003eShells: 3\u003c\/p\u003e\u003cp\u003eTemp: 240 C (Can be simply 200 C)\u003c\/p\u003e\u003cp\u003eInfill Type: Hex\u003c\/p\u003e\u003cp\u003eInfill Density: 20%\u003c\/p\u003e\u003cp\u003eRaft: None\u003c\/p\u003e\u003cp\u003eSupports: None  \u003c\/p\u003e\u003cp\u003e\u003cbr\u003eFor other printers and materials, the chief concern is producing a watertight or nearly watertight surface on the inside of the cup and siphon tube. If you have trouble achieving this, decrease the layer thickness to 0.1mm and bump up the number of shells. If this does not do the trick, tune your extruder for fatter extrusions.  \u003c\/p\u003e\u003cp\u003e\u003cbr\u003eThe STL file produces a ~8 cm tall cup at native scale. The STL mesh is dense enough that it should scale up or down very nicely.  \u003c\/p\u003e\u003cp\u003eThanks to \u003ca target=\"_blank\" rel=\"noopener noreferrer ugc\" href=\"https:\/\/www.thingiverse.com\/jsteuben\"\u003ejstuben\u003c\/a\u003e on \u003ca target=\"_blank\" rel=\"noopener noreferrer ugc\" href=\"https:\/\/www.thingiverse.com\/thing:123252\"\u003eThingiverse\u003c\/a\u003e for the original design!\u003c\/p\u003e\u003ch4\u003eFake Devious Pythagorous Cup\u003c\/h4\u003e\u003cp\u003eThe \u003ci\u003eFake Devious Pythagorous Cup \u003c\/i\u003edoesn't slop the water from the bottom, instead, it acts as a normal, drinkable cup.
