TLDR:

• Super slim retainer case, only 17 mm external thickness
• Fits one retainer
• No extra hardware or magnets required
• Super easy assembly
• Satisfying snap closure
• Snug close

This is a slim retainer case that I designed to fit my bottom retainer. It is only 17 mm thick, and does not have any bulky hinges. It does not require any pins, magnets or extra hardware.

It will most likely only hold one retainer, either an upper or lower, but not both! Please measure your retainer to ensure it will fit. The internal dimensions are 68 mm x 45 mm x 13 mm. If people like this design and need a bigger one, then I can make one, just leave a comment :)

The two halves can be assembled very easily by snapping the hinges together.

I printed this out of Transparent PETG, and I have not tested it with PLA. Let me know if it works with PLA in a comment below, thanks!
