Edited Sunglasses Visor Clip

This isn't a significant change from the original ( https://www.thingiverse.com/thing:2545456 ) by droton, but I added a ridge to it so the sunglasses (or my regular glasses) would "clip" into the clip.

I was was driving home from work in the fog that comes from teaching middle school all day, and I almost had a heart attack when my Oakley Gascan sunglasses landed on my head as I was coming up to a stoplight. The original clip had been doing an amazing job, but I think the arms on my sunglasses were a little too thick for it, and the arms on my normal glasses were a little too thin.
When I got home, I used Microsoft 3D Builder to merge a small cylinder with the section that holds the glasses. My sunglasses will still shake loose and move around a bit, but the ridge now prevents them form falling. I can now also use the visor without worrying about them coming down.
