This is an enclosure I came up with to house the main board and a Raspberry Pi Zero WH for my Ender 3 after updating to Klipper firmware. Klipper does not utilize the main board sd slot so I made a nice uniform front face. I also made the enclosure accessible from the top or the bottom. It uses a 4020 fan that is just slid down over the pins. This has worked well for me with the fan pulling air down and out of the enclosure. I printed at 10% infill, 0.2 layers, 4 bottom 5 top layers, 2 perimeters.
