Assemble your crew
See the components list for links to what I used.
You'll need:
- A Raspberry Pi Zero 2W (and SD card)
- A 7" HDMI display
- PCSensor-compatible USB foot pedals
- 5x7" picture frame glass
- 1/4" heat set inset connectors (at least one, probably several)
- Cables:
  USB OTG
  Female Micro USB to 2x Male Micro USB
  HDMI to Micro HDMI (optional: use flat right-angle cables for best fit)
  Micro USB female to male (optional: use flat right-angle cables for best fit)
If you want to mimic my tripod and camera mount:
- tripod
- 1-2 11" camera flash bars with screw mounts
- Optional phone camera mount

Print the case

The STL file is in the GitHub repository.
I printed this on an Ender 3 with no raft/skirt. The only support that should be needed is on the open sides of the case and the upper section of the cutout (above the hole for the camera). The angle on the back of the case is 45 degrees and should be printable without support.

Connect cables

Toss everything into the case

I had to do a bit of Dremel work on the front and back to get my monitor to fit (due to bad measurements on my initial model). I've corrected these and it should work with little or no modification now.

Dress cables and connect monitor
6

Assemble tripod

This might require some experimentation (and swearing) to get everything lined up. I had to print a small support structure to raise the camera mount a bit. This is just a rectangular solid with a heat-set inset on the top and bottom to allow it to screw in.
7

Connect camera

I use DroidCam and OBS to capture video from this.
