I made this wallmount for my trusty safety squints so I got them where I need them on my tool wall.

The thing consists of two parts: The tip is removable so to give access to the screwholes.
I mounted them with two 30*20mm screws.

They work well with my safety glasses though I haven't yet tested them with a whole lot of different glasses. You can tinker with the proportions to make it fit with your respective glasses.

//I guess it would give a better fit if the recess in the back would be flat instead of curved but I am too lazy to incorporate that now :)
