Raspberry Pi Zero Cooling Fan Bracket

The Quad-CPU Raspberry Pi Zero 2W is a pretty powerful beast for its size. However, if not properly cooled it will throttle its CPUs at about 80 deg C: https://raspberrytips.com/raspberry-pi-temperature/

This fan assembly helps you to push the Pi Zero 2W to its limits, in particular if you are running it at high ambient temperatures and/or applying overclocking. It fits the Pi Zero W and the Pi Zero as well.

It is an improvement over my previous design https://www.thingiverse.com/thing:6500953. You will find there some Python programs to monitor and control the CPU temperature. Some electronics and soldering will be required to on/off-control a two-wire fan via the Python program fan.py . Variable-RPM three-wire fans are not supported by my electronics and software.

In my previous design the fan motor's back is shadowing part of the heat sink, limiting the cooling effect. This new improved design is directing the fan's air more efficiently over the Zero CPU's heat sink.
