Replacement CR-6 SE OctoPi Tool drawer

thingiverse

A replacement drawer tray for the CR-6 SE to take a Raspberry Pi 3A+ and a PiJack power adapter board (which will take up to 32v input) to run OctoPrint. The USB ‘extension’ is wired leaving out the V+ connection so the Pi can’t back power the printers control board. There are a couple of magnets mounted in the end of the drawer so that it ‘latches’ just like the original drawer. In the tool side it’ll take five SD cards, a couple of spare nozzles, the supplied nozzle wrench and spanner to adjust the eccentric nuts and a screwdriver / hex key tool that is normally intended to be used for maintaining drones but has all the sizes of tools you could ever need for the CR-6 … The idea is I'll mount a DC Jack in the front of the CR6 to give a 24v outlet so I can then use a couple of short (20cm) cables to loop power to and data from the drawer to the printer and have a nice little discrete self contained Octoprint installation totally inside the CR6 as well as a properly useable toolkit but it also means that the OctoPrint instance can either be powered from an external wall wart PSU if I want OctoPrint to - say - switch power to the printer using a smart socket. I've included a list of all the parts that I used in the drawer build in the accompanying .txt file.
