Customizable Nesting Eyeglass Case

This is the evolution of my Simple Eyeglass Case. I know that eyeglasses come in all shapes and sizes so I built this for your customizing pleasure.

I've had the best results with 0% infill for flexibility. You may need to play with the buffer variable depending on your printer and filament. TIP: stop the print 1/3 way through to test the nesting friction.

Added a lip on the inside half for easier gripping.
