Needs some 3x8mm and 4x8mm screws - watch out that those attached to the powersupply do not reach to far into the powersupply - otherwise one risks a shorted circuit which might even end deadly.
For connecting to the mains I reused the original switch and plug.
For connecting the printer I used https://www.printables.com/model/91517-wago-221-2411-plate-mount/comments/1237940
I printed in PLA with 0.3mm layer height and 20% infill.
The WAGO clips could have more distance
The switch could sit tighter
The internal cabling should have black/red for -/+ (instead of blue only)
The front plate has +/- embedded (by moving it one layer up) - should have printed that in dual color mode
