Yet another SKR 1.3 and RPi enclosure

thingiverse

This is yet another case of SKR 1.3 board and a RPi (2B in this case). I made a wood+corrugated plastic sheet enclosure for my Ender 3 and needed a case for housing these. I also wanted to mount the case outside the enclosure (at the back). The case features a 120mm fan on the lid, to reduce noise. The fan is powered by the "12/24 out" pins (via a LM2596 buck converter stepped down to 12V). The case has a mount for a dual relay board, one of which I am using to control the lighting in my enclosure (via the RPi gpio), using the OctoPrint enclosure plugin. There is also a slot in the case for a standard push button to control the lights outside of the OctoPrint interface. The RPi and the SKR 1.3 are both driven by the stock power supply. The power supply case has been changed too. I have used https://www.thingiverse.com/thing:2949139 for the 92mm fan replacement and https://www.thingiverse.com/thing:3843968 to mount the PSU to the back of the enclosure. I mounted an XT60 female plug in the case using this - https://www.thingiverse.com/thing:3530615 The enclosure lighting is connected using 2 separate XT30 plugs (one to LED power supply and one to the LED strip, with the relay in between). The XT30 insert I used is also in the files section. I used M3 socket head screws to mount the SKR, RPi and the relay board. For the buck converter, I just used some hot glue :) For mounting the lid, I printed 3 copies of the "pin", two of which serve as the hinge pins and one is the locking pin on the opposite side.
