Remix of Raspberry Pi 4 case (40mm fan) (Original by John_Sinclair)

thingiverse

This remix of John's case design adds a cover for the fan to the upper section. I sliced it in Cura using John's print settings with one difference - I used the tri-hexagon infill. I printed it on my Anycubic i3 Mega printer. The design allows for plenty of airflow without the risk of small objects or fingers obstructing the fan. To add temperature control to the fan, I followed these instructions: https://howchoo.com/g/ote2mjkzzta/control-raspberry-pi-fan-temperature-python To add a power button and an LED power indicator, I followed these instructions: https://howchoo.com/g/mwnlytk3zmm/how-to-add-a-power-button-to-your-raspberry-pi To accommodate the button, I drilled out the egg timer shape from the middle of the hole above the place where the Pi's USB-C socket would be. This design allowed me to overclock my Pi 4 4Gb to 2Ghz and the CPU to 700Mhz, with the fan cutting in if the Pi reaches 65 deg C and cutting out when it lowers to 55 deg C.
