Extra small extra macro keys v1.0

================================================================================

After my previous macro key project back in January that used full-size arcade
buttons, I was itching to make a more compact set of macro keys.

I bought a sample set of different Cherry MX keys (https://amzn.to/2L9lrz9) –
these are the mechanical part of the keys, complete with key caps, but without a
full keyboard. The keys are fully functional, so you can solder some wires to
them and use them in place of a regular momentary switch in any project.

Since the last macro keys project I’ve bought a couple of Arduino Pro Micro’s
which handle HID a lot better, and are quite cheap. You can get them as single
boards, or in packs of multiple boards from around £7 per board on eBay
(you can find the specific boards I ordered here: Arduino compatible Leonardo Pro Micro 5V (https://www.ebay.co.uk/itm/Arduino-compatible-Leonardo-Pro-Micro-5V-Multi-packs-ATmega32U4-UK-Seller-/322529460147))

The print didn’t turn out great, with some delamination and other problems
causing roughness, so I figured I would try finishing the print with some filler
and paint. This worked to a point and sanded down really smoothly, until I
accidentally got the whole thing wet and the filler disintegrated (!)

The design was also not perfect, with the angle of the keys being a bit too
steep. So back to the drawing board!
