Corne Slim Case

A minimal, slim bottom case for the [Corne keyboard](https://github.com/foostan/crkbd) (without the 6th column).

It has 2mm clearance between the case and the PCB, which is enough for hot-swap sockets to fit.

I have a [new version](https://www.thingiverse.com/thing:49196250) with a top plate as well.

Hardware needed:

- M3 x 3mm x 5mm inserts
- M3 x 4mm screws.
