I recently noticed I was experiencing difficultly reading highway and street signs while riding my motorcycle or driving a car. A visit to the eye doctor determined the symptoms I was experiencing were due to the onset of cataracts (my distance vision was deteriorating, but my close up vision was improving).
For riding and driving, I obtained prescription sunglasses that worked well outdoors, but not so good indoors. So I decided to obtain prescription glasses for indoor use in order to watch movies or television. Unfortunately, after a few weeks of carrying them in my pocket, they broke.
So, I designed and printed this thing to hold my new glasses along with the included soft bag that doubles as a lens cleaner, safely in my pocket. Problem solved (well the broken glasses, not the cataracts).
Print one each of "Case.stl" and "Lid.stl". The lid slides over the case with a friction fit.
