Tronxy X5S Electronics Box for SKR 1.3 and Raspberry Pi.

Having a bit of an upgrade fest on my Tronxy X5S, one of the things that I wanted to tidy up was the quantity of electric string adorning the machine. I've upgraded the original controller to an SKR 1.3 and also wanted to use Octoprint. The separate screen controller, Mainboard and the Raspberry Pi was going to need housing somewhere, as well as cooling with the switch to TMC 2208 drivers. The design concept was it needed to fit on the front of the machine to give clear access to the controller but not protrude significantly as I am planning to enclose the printer at some point in the future. The only projection from this design is the control know which I plan to let project through a drilled hole in the door of the enclosure to enable operation from outside. The case utilises a 2050 axial flow fan to draw cooling air into the case through the six inlet ports at the lower edge of the case. These direct the air across the Stepper driver heat sinks ensuring they get maximum airflow. The Raspberry Pi sits in front of the fan and the circulating air should ensure it remains cooled too. I recommend fitting heat sinks to the Pi processors and regulator chips to prevent auto-throttling. I intend to mount a PiCam on the bed carriage where there's a couple of screw holes conveniently unused for the cable chain on the rear of the printer. To this end, there is a small slot in the base for the PiCam ribbon cable to exit. I'm printing the 3rd version of the box as we speak so haven't fitted it fully yet but thought it might be of interest to some folks who want to try it. If you have any suggestions, feel free to comment.
