Magnetic Fragrack

I used common sized magnets from amazon, the magnets are easily changed in a 3D suite, all you need to do is make sure they are STRONG and you'll need to pause print to insert magnets, of course!. The rubber O-rings I used were 25x3.1mm in the rubber O-ring kit I linked, they just pop into the circles on the glass side of each outer magnet and inner magnet pieces. You can use a bit of superglue for the dovetail but it is stable pressure fit.

I used these magnets and rubber O-rings::
