My first try at a DIY Macropad. It has host-swap support for both Choc and MX. Not perfect but a good start

Welcome to my first try at a DIY Macropad. While it's far from perfect, it's a start.
Building your own is possible, though I wouldn't wholeheartedly recommend it unless you're are willing to make some sacrifices.
Hardware
My version is compatible with both Choc and MX switches using hot-swap sockets. As long as you solder the correct socket, you can easily swap your switches.
If you decide to build your own version make sure to solder the IO expander in the correct oriantation. In general it would be best to have the Fusion project open as a reference
I originally planned to make this Macropad wireless, but that ultimately didn't work out. I tried reflashing an HC-05 with firmware that should make it HID compatible, but I couldn't get it to work. For this reason, most of the components are not necessary.
I would recomend printing the enclosure in PETG. It uses a clip fit with some thin walled clips which would end up breaking of if I tried using PLA.
Firmware
In terms of firmware, I was forced to create my own. It's currently missing a lot of features, but it's a work in progress.
I wasn't able to get KMK to work since I used an IO expander without a keyboard matrix. As I have never used KMK before, I wasn't able to configure it. However, if you're able to do it, I would love to hear your input. It should be possible.
