Flat folding crkbd case

## Flat folding crkbd case (WIP)

Not a remix, but definitely inspired by [this](https://www.thingiverse.com/thing:5333266).

## Features:

* Flat, 2 Layer design: Vertical part fully folds into base for extra flat design.
* Hinges designed to use 1.75mm filament as axle.
* Vertical part has notches for height adjustment, and a solid locking mechanism at the top.
* Slots for magnets (5x1.8mm) to hold everything together when closed

## Caveats / ToDos
* too thin. Hinges tend to break and it is a bit wobbly, so next version will be beefier
* doesn't enclose PCB, could use some walls
* end of vertical height adjustment piece prints as overhang
* more magnets to hold things shut more securely
* indentations for rubber feet?
