Tamper proof dice cup

I just made this while waiting for the order for my 3d printer to go through so I have not yet tried it, my idea however was to create a cup printed in a rubber like material TPE or TPU that would put an end to the bickering about who cheated with the dice.

Be it Yatzee, Monopoly or D&D there is always someone who claims cheating when they lose.

Print it, try it, tell me if it worked.
