This mount is a modification, from another another great design, that moves your xtouch screen to right screen the P1 screen. Moving the screen to the side allows it to be out of the way from the glass, AMS, etc.
Since the xtouch will need a USB cable, this was designed to be used with a spacer like https://makerworld.com/en/models/159792#profileId-175411 . There is also a longer extension to keep the usb cable out of the way/hidden. Plus there is a cutout on the bottom to allow for the SD card and DuPont ports (temp or LED)
The back cover/screen will require 4 - M2.5 x 8mm (or even 10mm) screws.
