Secure Close Ring Holder

My aunt asked me to make a ring holder that will stay closed even it gets knocked over.  While this one still might pop open on a good drop it should do better in most cases than most of the simple ring holders out there.  

Printed with 3 walls and 20% infill.  Recommended printing the lid flat so it is stronger.  

The main box only needs supports where touching the build place for the feet recesses.  If you don't want to add rubber feet you could just move it down through the build place 1mm and not use supports.  The lid will pop into the side with the large dimples and then the other side will open and close with a snap.
