I designed a mox ruby pendant and I wanted to create à deck box with a opening mechanism. You just need to press the ruby to open the box. The box can contain 3 decks with his own compartment.
To assemble the box, you need to glue the gem to the moving part and fit the cylinder in the hinge.
!I did not test it, so if there is a print problem or a fonctional problem you can tell me in the comments !
