Printer switch/outlet box

This is a box I designed to enclose a switch and outlet (post switch) for powering my 3D printer setup (including RPi3). I had originally had a box just for this push-button switch, but once I added a Raspberry Pi to the mix, I needed a good way of powering that as well.

I was lazy on this design, so rather than making this proper, the outlet is attached with nuts/bolts through the "faceplate" side of the box. I also just made the "Lid" that holds the push-button switch to be glued on, once printing is complete. I think there would be room (although it would be challenging) to put it all together through the holes, so you could probably print this as one piece, but you would need a LOT of interior support, and I didn't want to deal with wasting all that plastic, or having to remove it through the holes.
