Google Glass Adapter for Prescription Glasses v.2 (Credit to DDRBoxman!)
thingiverse
The original adapter was on Thingiverse as an unformatted .scad file with a small opening for the glasses. It was modified to an STL file, and the opening enlarged according to my glasses size. Measuring your own glasses' arm dimensions is advised before editing the design in a program. Additionally, a Reddit post was initiated at http://www.reddit.com/r/googleglass/comments/1rh62f/how_many_people_would_be_interested_in_getting_a/ to gauge interest for potential buyers without 3D printers.
