Anet A8 PSU Small Frame Fan

A small frame fan holder for the Anet A8 power supply unit. I am using a 10k thermistor, a 2N2222A transistor and an Arduino Uno to control the fan speed for constant cooling. It mostly helps with ABS. I am using a small 40x10mm fan strategically paced on the face of the PSU so it will maximize the cooling. The circuit board is a 3cm x 7cm one but you could easily modify this part to make it a different size. Also if you do not need to regulate the speed of the fan then the upper (arduino) part
