Coffeecup Gimbal (Q904900)

A simple coffeecup stabilizer. Of course it is preassembled; 3-d printable without support. P.S. It did not work very well. Ideas are wanted. I suppose the liquid surface must be well below the pivots. P.S.2 I finally noticed that a string is enough for a gimbal, and actually found the exact design: http://www.core77.com/blog/object_culture/edmund_scientifics_no-spill_coffee_device_26583.asp
