Updated 28th Nov 2017 - Medium Case added 160.8 x 55.8 x 45.8 (mm)
I seem to get through glasses cases like hot dinners so I designed my own which I can print at any time if I break another one :)
This is designed for a small pair of glasses but I may upload a medium and large version. The filament used in the pictures is Filamentum Galaxy Vertigo for the outer case and Sainsmart Blue TPU for the inner lining.
This case is made of 4 pieces; 2 outer shells which have a hinge; 2 inner linings which can be printed in TPU for added protection. Using these will reduce the internal volume. I recommend a tight fit with your glasses so they do not rattle inside the case.
The hinge pin is just a length of 1.75mm filament, I recommend PETG but any stiff filament will work.
Magnets required for the latch are 8mm Diameter x 2mm Thick, just glue them in with superglue.
