Google Glass Lens Mount

A 3D printed part that mounts a lens to Google Glass
------------------------------------------------------------------------------
I am nearsighted in my right eye, which means the Glass display is
blurry. This lets me add a lens to make Glass work for me, and it
allows me to remove the lens easily so others can try my Glass.
(I don't wear glasses normally, because my other eye is not
nearsighted.) It printed well on my Makerbot Replicator 2X.
