Raspberry Pi cooler

A fan design for the raspberry Pi (up to RPi 3B). it uses a very common 40x10mm fan with angle duct (I think its the same one used by Creality to cool the ender3 series).
I also made another version that really cools anything above the RPi3, including the RPi4, it uses a 5015s blower fan. it keeps the newer Pi’s very cool (no more than 20 above ambient under full load. )
