This is a remix of a display mount for Lack that was originally for the left-hand side only. The Creality mount isn't symmetrical, so this required more mesh editing than just a mirror, and so I uploaded it to save others the effort.
The chamfer on the keyholes couldn't be recreated without having a STEP file, but everything else is the same. I've printed it, and it fits snugly. Enjoy.
Printing:
I printed it in PLA+, but I don't think it really matters, I think anything is strong enough for the purpose as long as you give it sufficient walls and infill. I did:
.6mm nozzle, .2mm layer height, 3 walls, 6 top and bottom layers, and 30% cubic infill.
I don't think it is particularly sensitive to settings, so knock yourself out.
