Make grips for glasses' arms

The grips on the arms of my glasses are short so the metal rubs against my head all day, every day. This makes the coating on them rub off, damaging the frames and leaving an ugly residue on the sides of my head.

I used some sugru on each side to extend the grips much further along the arms. I let the sugru set then used a craft knife to trim it and make it look much nicer.

This solves the wear issue and had the added bonus of making the glasses grip my head better!
