Updates to come (02/08/2017)
Soon I'll add a slot for a key switch, so it will make the machine child safe when turned off. At this moment I'm working on a new cover, which will have a hole for a 85x46mm power consumption display. Unfortunately, there's no way to fit both with the stock PSU height.
Uploaded a new version for short flange S-240-12 version. Moved all the holes 6mm higher, and also the cut where bottom side of the flange rests. Some PSUs could have that short flange, at least in the US. Measure yours before choosing normal flange (approx 18mm) or short flange (approx 12mm). Thanks to @airrelic for the input.
Uploaded a new version. Changed some dimensions. Now the side bolts thread in a M3 nut, instead of in the piece itself.
This is a PSU cover for Anet A8. It fits for S-240-12 PSU and allows you to install a rocker switch socket like the one you can see in the attached picture.
Doesn't need supports, brims, or whatever...
It's reinforced in the inside. I would recommend printing on glass + hairspray, so the front part looks smooth and clean.
You can easily bolt them to the holes in front left top, and the ones in right side front top.
It should be printed with the front face on build plate. No supports needed.
The switch itself
1x M3x30mm bolt
2x M3x12mm bolts
2x M3 nuts
1x 5x20mm 250V 3A Breaker, Fast Blow if possible. (3A ONLY FOR 220V)
Some L, N and E wires for the AC part. (COLOUR CODE DEPENDS ON YOUR COUNTRY)
Faston terminal connectors.
Soldering iron and flux (optional)
It works for 3 Pin IEC320 C14 Rocker Switch Socket, like the one in the link below:
DOES IT WORK FOR 110V?
I haven't tested it for 110V, so input from any place in North/Central/South America would be most welcome. As long as the PSU is set for 110V and the switch works for 110V and is prepared to deal with a higher current, it should work. Ask your electric stuff supplier just in case.
BobPantz made this remix for Multicomp JR-101-1-FRSG-03 Rocker Switch Socket (UK)
If you make one feel free to hit "I made one" button. Feel free to give feedback :D
ABOUT THE SWITCHS
Some switchs out there have three terminals, while some others have four. For that reason, I won't provide any wiring diagram. The wiring info should be provided by the manufacturer in the datasheet. Sorry for the inconvenience.
Of course, this mod demands some AC wiring. This step can be dangerous and could cause major injuries or even death, as well as a fire or damage to your printer or any other part of your home.
Do it at your own risk.
Safety measures must be taken.
Never work on the wiring with the printer plugged.
Check the datasheet of the manufacturer before doing the wiring.
Check the wiring with a tester before switching on.
