I always wanted to have case for my spectacles in the correct size. Usually they are all too big and clunky to actually use them, especially in confined spaces. Now i just design and print them myself.

This one is for RB 5114 2034 52-16 135 .

Printing should be straight forward. If you have issues with the dimension of the bottom or top parts, you may just resize them in all dimensions slightly until they fit perfectly, but this was not necessary with my printer and standard PLA.
