I printed the [Better Oculus Quest 2 Magnetic Lens Adapter](https://www.thingiverse.com/thing:4781759) by HaroldHyrax, but the magnets I have didn't fit well. Rather than resizing the holes, I decided to add a peg to the base that slides into the hole in the top piece.
Then I found a remix by [seethebridges](https://www.thingiverse.com/thing:4630689) that does exactly what I was thinking. However, that was based on the [original version](https://www.thingiverse.com/thing:3659124) by jegstad, and my [Zenni](https://ca.zennioptical.com/p/metal-alloy-full-rim-frame-with-spring-hinges/5500?skuId=550021) lenses (-2.50 and 1.57 mid-index) were just about touching the Quest 2 lenses. Also, I didn't like that the top piece was only 3/4 of a circle (I assume to make more room for noses). It's fine when the lenses are in the Quest 2, but they're less protected when sitting on the table.
So, I went back to HaroldHyrax's version and added a bevelled 5mm peg, with a corresponding 5.2mm hole in the top piece. Lots of space for thicker lenses, and no need for magnets. As with the original versions, you'll need to use the glasses adapter for your Quest 2.
Now I just need a case to hold the lenses when I take them out. Time to start looking for a box that I can remix!
