This is a remix of a vital part of Stilwell's power switch mod (https://www.thingiverse.com/thing:4864993) - the actual relocated switch mount on the front end of the right base extrusion on the printer. Why? Because ... apparently Creality uses different parts on the same printer, maybe dependent on where it ships, whatever. On mine I found the original switch would never fit Stilwell's switch mount, so I did this remix.
There's three iterations - two recessing the switch as to avoid accidental activation (my printer sits on my "everyday" desk and I do not want to accidentally switching it off while a print is going on). One recessed version is narrow, one widens up a bit - whichever you like best. The third iteration adds a flip cover (thus keeping the base plate sleek), the cover is best printed in a transparent filament (it will not become see-through, unfortunately). The hinges line up perfectly with the extrusion slots, so if you have fitted any of these fancy extrusion slot covers you maybe want to print the flip cover in the same color. I pondered about PIP hinges but decided against - one, to open a possibility for multi color / multi material printing, second becaude it is a functional part and I choose strength over cleverness of design - just use a 2mm drill and use the good old (but extremely reliable) filament hinge: push a length of filament through the holes and flatten the ends with a heated nail head. This will give you a very strong and lasting hinge.
All three parts are push-in and fit quite snug, the may require some careful wiggling to seat them properly but in the end they will just slot in - and stay there, no shifting about or anything (I feel that for a switch, or in fact ANY electrical fitting, you do not want any movement or falling out or what).
