Power Receptacle box and switch box

I needed a safe receptacle box for the house input power and main power switch that was relatively close to the meanwell power supply (PSU) on my Ender 3 V2 when I expanded the printer with the enderextender pro kit (and needed to move the PSU).

The power receptable opening is approximately 31 mm x 27 mm.  (I had to trim about a ½ mm to make mine fit.  Two holes spaced 35mm to mount the switch using original screws.

The switch receptacle opening is approximately 11mm x 30mm.

Shell thickness is 1mm which is perfect for my switch that mounts with tabs.

I mounted this to the back of a 4040 extrusion that also has a 2020 stiffener.  Through bolted to tapped M5 holes in the 4040.  I used 65mm m5 socket head cap screws.
