About this 3D model

I like to have gum on my pocket, but the 18's package gets shredded with my keys and knives and whatnot, so I decided I would make a rigid case for them. It works great, my first iteration has lasted for more than a year. I changed a few things so the gum wouldn't fall out of the case. BTW The hinges are pins that are cut to size and kept in place by a small blob of ABS goo.
