TPU Glasses Case (no button)

My wife needed a decent and small glasses case, so 3D printing to the rescue! This is designed for TPU; doubt it would work correctly with non-flexy filament types. NOTE: you need to affix the button manually afterwards. There are NO buttons associated with this model. We used a Snap Button tool that affixed a small plastic button. Print, fold down the flap, affix the button. Done! See the assembly image for details.
