Pythagorean cup #3 (without a center pole, double ring)

This is an improved version of the one I made earlier (thing:5859929).
The previous one sometimes leaked liquid, but this problem is reduced by doubling the ring-shaped part.

This is a Pythagorean cup without a center pole. The basic structure is based on thing:123252 by jsteuben. It has a small and simple shape so that it can be easily used as a teaching material.

If you put a small amount of liquid in the cup, the liquid will not leak and you can drink normally. If you fill the cup with liquid, the liquid will start leaking out of the cup and eventually all the liquid will be gone.
It is a model that allows you to experience the proverb "grasp all, lose all".
