I could have used a power strip with a switch, but this way it has less tangled wires and plugs and looks much better too.

For this model, you need some electric hardware, I bought it at AliExpress:

• EU power socket for the Raspberry Pi power supply
• C14 Power connector for the power input (the AC-06A)
• Switch with integrated light
• 4.8mm female crimping connector (the red ones)
• 5x wire connectors (choose your color)
• 2x 8mm gasket rings
• Two cable with C13 plug, shortened to ca. 30cm (I took some that were lying around)
• Two cable ties to secure the C14 cables

To assemble the parts, you need a few nuts and bolts.

• Interface side
  • 8pcs. 3mm hexagon nut, inserted while printing, gcode has a pause on layer 36
• Switch side
  • 6pcs. 3mm square nut, inserted after printing
• EU power socket
  • 4pcs. 3mmx8mm Allen bolt
• C14 power socket
  • 4pcs. 3mmx6mm Allen bolt
• To screw the two sides together
  • 4pcs. 3mmx8mm Allen bolt (I used black ones)
• To mount the power box on the enclosure
  • 1pcs. 3mmx8mm Allen bolt
  • 1pcs. 3mmx6mm Allen bolt
