This is a custom case I made for my 3D-printed eyeglasses. https://github.com/Giraut/3D-printed_eyeglasses

I made this custom case for my 3D printed spectacles:

Custom case

It holds the glasses by the edge of the frames, so the lenses are suspended above the bottom of the case without touching anything and no padding material is necessary to prevent scratching.

And being specially sized for those glasses, the case is no larger than it needs to be.

Did I mention that I love 3D printing? 🙂
