Raspberry Pi 400 Holder / Mount for Waveshare 11.9" Capacitive Touch Screen LCD, 320×1480, HDMI

Non-destructive: no adhesives or screws directly on the Raspberry Pi 400

Holder consists of left, right, middle, and display held together by zip ties and M2 screws.

Hardware:

• Raspberry Pi 400
• Waveshare 11.9inch Capacitive Touch Screen LCD, 320×1480, HDMI

Also need:

• zip ties to hold the left and right pieces of the mount together (make sure to use a thin zip tie that fits through the holes)
• M2 screws, nuts, washers to hold the left+ middle+ right+ display+ pieces together

To fully replicate my setup:

• 30cm micro-USB cable for touchscreen power and data
• 20cm HDMI to Micro HDMI cable
• 20cm USB-C data+power extension cable

The 400 acts as a USB HID keyboard when connected to another computer, e.g. my Mac or Windows PC, which also powers the 400.
I got the code from: https://github.com/Gadgetoid/pi400kb

The plan is to turn the touchscreen into something like a Stream Deck / Macro keyboard / password manager that works with any computer it's connected without the need of any software on the host machine.
