This is a replacement display mount for the Ender 3 and enclosure for the CYD (cheap yellow display) running CYD Klipper. It's a direct replacement of the stock display mount using the existing bolts to the frame.
4 x M3x12mm bolts are used to attach the rear backplate to the cover. You should be able to use countersunk or non-countersunk.
The opening is in place to line up with the USB port on the right-hand side for powering the device.
The logo/printer's name was a 1 layer inlayed (printed first) following these directions.
