I love the case design by LukyChoose, but I keep breaking the hinge. I've printed 3 or so cases over the last 7 months and last week dropped and broke the third...

I've modified the case so that instead of working like a clamshell, the case is two separate parts held together by magnets. I've dropped this case a few times already and can happily report that it still works fine and the four magnets held the case shut.

You'll need to print two halves. I've included a version with no logo in case you want just the logo on top, or if you want a generic case with no logo at all which can be used for retainers or other dental inserts. I personally like having the logo on both sides.

I've also created a little spacer file that can be used to make sure the magnets are closer together, as the ones I bought seem to sink a bit too low into the case for the hold to be strong. I used one spacer in each hole in one part of the case and two spacers in each hole in the second, and that makes it so the magnets are the perfect distance from each other to ensure a strong hold. You might need to play around to find the correct amount (if you need any at all) and that will depend on your printer and its settings.
