A replacement case for Invisalign or other retainers/dental inserts.

Rather than a clamshell design, this case is printed in two separate parts and is held together by four 5x2mm magnets. I've dropped this case a few times already and can happily report that the magnets held the case shut, preventing my retainers from falling on the ground.

You'll need to print two halves. I've included a version with no logo in case you want the Invisalign logo just 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.
