Ender 5 Raspberry Pi 4 | 3 Electronics Box

Last crawled date: 4 years, 3 months ago

This is a little box I threw together to house my Raspberry Pi 4 in the frame of my Ender 5. It can hold a few relays or buck converters and has an internal wire strain relief for the power plug (just zip tie the cable to the support).
It's big enough to house a Raspberry Pi with a fan hat (40mm internal height, minus standoffs for Raspberry Pi). I couldn't find a case that would accomidate the hat linked below so, I made my own. It has a port that can be capped for the Pi cam cable and large holes in the bottom to allow for wires to exit as well as two additional cut outs for holes in the top and vents. There is also a removable panel in the back for access to the Raspberry Pi's SD card.
I printed this without supports except for the channel on the frame. This will all print on a stock Ender 5. You don't need to print both the cap and the Pi cam cable chain adapter. Those both go into the hole at the top.
Connect the box and the frame to the aluminum extrusion via t-nuts and M3 screws. The lid for the box is held in by the channel in the frame and using heat-set inserts in the box with M3 screws. The panel for the Raspberry Pi SD card is held on with short M2 screws.
There are extra holes for the frame and box, I definitely did not use all of those attachment points but, wanted the layout to be flexible.
I mounted this at the back of my Ender 5 but, It should work behind the LCD in a stock configuration. You'll probably need to customize the frame so that the lid connects to the frame. I've included a STEP file and Fusion 360 archive file if you want to mess with the design.
