Raspberry Pi and Fan Mount (Scaled down + compat with the rack mount)
thingiverse
I reduced the original z height of the @krc92 fan mount to fit my needs (I had only 20mm M2.5 screws). Tested with a raspberry pi 4 (and a pi 1) with my Noctua 40mm. I also removed 2 of the 4 legs to fit the @Merocle "Raspberry Pi 4 2U rack-mount Mark III for 18 Pi" 2U rack unit. With such a fan, you need 2 blades bodies for one Pi. NOTE: The (messy) wires from the pictures are for a DS18B20 temperature sensor (See https://www.thingiverse.com/thing:5424464) and a DHT11 humidity sensor ;-)
