The cutout in the aluminum extrusion for the cables on the Elegoo Neptune 2S is a bit sharp on my printer and could cut into the wires if moving the printer around and modding.

My print was done at 0.2 layer height with 3 walls but it left some artifacts around the tabs, 1 wall should print cleanly.
It's pretty straight forward but here is a video if you want to see further commentary and installation:
