Waterproof CR123A Case

This is a waterproof case that holds two CR123/CR123A batteries. It seals using O-rings. I submerged it in water for about three hours with a piece of paper in it without any leaks, so it seems to work as expected.

Suggestion: If you only want a case for one battery, simply drag half the body of the case below the buildplate in Cura. This will allow it to only print the top half of the case. Turn off supports if you decide to do this.
