Pythagoras cup (戒盈杯)

Well known tricky cup as a Pythagoras cup (or 계영배, 戒盈杯, Greedy cup )

1) I tried to hide Siphon into handle

2) Since it's 3D printing, leak happens.
(!) and some of them are kept between inner wall and skin
(inside of structure, the area of Fill. Check the photo)
inside of Siphon as well.
Wash and Dry properly after use to keep clean (!)
