M8 Headless case/controller

A case that I put together to hold a Teensy 4.1, a USB controller board, a USB hub, and an extra USB C port for a self contained Dirtywave M8 headless build.
Everything fits together well. I did have to file the USB ports and the SD card slot a tiny bit to get a nice fit. It's held together with 4x M3 machine screws that just tap into the holes in the corners.

#### Components
* [Control board](https://www.amazon.com/dp/B083RTPVVQ) - cheap USB joystick board from amazon. There are probably better ways of doing this, but I've used these before so it made sense to me. I pulled all the plastic connectors off and just soldered everything together
* [Adafruit CH334F Mini 4-Port USB Hub](https://www.adafruit.com/product/5997)
* [USB C port](https://www.amazon.com/dp/B09KC1SMGD)
* Keys are Kalih choc low profile just like the real device. I used quick disconnects to make switching things around easier.
