Pythagoras' Greedy Cup
thingiverse
Here is my take on Pythagoras' Greedy Cup. If you fill it above about 60%, it will dump itself out of the hole at the bottom. I tried my best to make the shape tricky so people might not notice the holes until they've triggered the effect. Side Note, does anyone know how to set default views in Thingiverse? For me, it's upright in both SolidWorks and Meshmixer, but on its side in the Thing preview window.
