this is a DC shunt display mount which is compatible with the new USB-style connection or the old style with multiple loose signal wires. the cutout on the side is placed to fit the USB location or you can feed the signal wires thru if you have the older style. https://www.amazon.com/dp/B0CZ36J9BY

the display snaps neatly into the box which you can mount with screws or zip ties.

Edit: don't print it in black PLA. it survived one sunny afternoon and warped badly. white PETG is the right material for direct sunlight.
