Replacement frames for Nike Eyeglasses 7100/1 001

Replacement frames for Nike Eyeglasses 7100/1 001. Same old story -- had a pair of glasses which the frame kept on breaking (at the bend on the arm). After a couple of times, parts were no longer available. Not wanting to waste a good set of lenses, I designed these. They custom fit my face and the arms hook around the back side of my head, keeping the glasses from falling off. Lenses are attached to the parts using M2 screws -- lengths will vary depending on the lens thickness.
1-7-2016 Update: Right arm now printed with Carbon Fiber. This is the one big feature of the Mark1 -- printing usable parts.
1-13-2016 Update: Now both arms have been printed with CF, much stiffer and fit better.
