Perfect fit for a new pair of glasses I just bought, but too small for all the others I own.
The interior is plain white PLA. I was afraid they would scratch the glasses, so I glued a layer of fabric I had laying around.
The outside is wood-like PLA with a coat of wood varnish.
I could not fit a 1.75mm filament in the hinge, so I used a straightened paperclip instead.
