Quest 2 58mm IPD limiting bracket

My IPD is 58mm, but that brings the lens so close together that my nose can sometimes bump the lens apart to 63 or even 68mm, especially when I am doing fast head movements, as is likely when I am playing the game that is the only reason to have a headset, Echo Arena.

This is not an ad for Echo Arena though.

This is, instead, a limiting bracket to try to hold the lens at 58mm IPD. It doesn't fit on top of the lenses, but actually slides down and tends to hold by friction. A piece of double sided sticky tape might help as well. It could probably go through a couple more design iterations, but it seems to work for me now.

Originally I tried building it by using/modifying:

But I decided I didn't want to clip on top of the lenses, so I ended up drawing this from scratch.
