OK, here is my remix of Ocie's fantastic box. Information from him for sure might supplement any questions that you have:

I have opened up the recess for most USB cables, and included an internal holder for the Bucks with openings for wires

I use the raspberry Pi primarily as a webcam, but its running Octoprint and can talk to the duet and control it just fine. I can also control a smart outlet with Octoprint on its own power supply.
