This is a custom PSU cover for my own HICTOP Prusa i3 clone. It includes holes for a pushbutton switch and AC receptacle I had on hand, as well as an Adafruit single channel relay for software controlled cutoff.

I also included a model without any hole cutouts so you can customize it for your own AC receptacles and switches.

The relay mount also includes a receptacle for using Stretch Magic to bring the relay status LED to the outside of the case(see the little 2mm hole in the corner)
