Pencil Crayon Case - PiP

I wanted a pencil crayon case with flip up holders like you'd see on a case made for drill bits.

The whole case prints in place.

It can hold 24 pencil crayons.

This is my first draft, and it could use a bit of refinement. One thing I'd like to add is a compartment for a pencil sharpener and it's shavings. 

Any and all feedback is appreciated.
