This is actually my 14th attempt at a Greedy Mug, but the first one I'm releasing to the world. Don't forget to check the sizing table among the Images, to make sure yours fits nicely in your hand.

Pythagorean (Greedy) Mug Features

Mug_PythagDuelNarrowingPipes.stl

• Unassuming, comfortably curved design.
• Slim walls help disguise suspicious intent.
• Hidden drain entrance is difficult to see on initial inspection.
• Identical twin drain-pipes help maximize drain-speed.
• Narrowing pipe just after the apex, helps ensure a complete flush, every time.
• Tilted floor ensures every last drop goes down the drain.
• Shower-head style base prevents fingers from blocking spills, and ensures maximum mess.

Boring Mug Features

• Externally identical to the Pythagorean Mug, but it won't drain your drink.
• Further confuse your victims by showing that you have the same mug, but yours doesn't leak.

Health Stuff

Don't forget, 3d printer resin isn't food-safe. And even if you specifically print this mug with food-safe plastic, it will still be very difficult to wash those little pipes. Unless you're very thorough in cleaning and drying the inner plumbing after every use, mold may grow in places that can't be seen. As such, this mug is intended as a novelty item, for educational and entertainment purposes only. Use with food may be a health hazard.

This design now stars in two videos by " The Action Lab " on YouTube. (No affiliation of mine.) Note that despite what the titles suggest, this cup is not especially dangerous... however the content-creator adds a few unorthodox features to make it more exciting! Here are the links...
