RV Fridge Fan

Thermostatically controlled 12V fridge fan.

I use threaded inserts on the middle piece so that the parts crew in from each end

I use a 5V thermostat board

Mini USB receptacle for power

Since the standby power is so low, will need a portable power supply that does not turn off when fan is not running.
