Ventilator controler (temprature controlled)

On/off switch for the main 12VDC cooling ventilator in the lower section of the Rostock max V3 and V3.2 so after a long print job is done the loud ventilator will stop keeping all the sleep needed people awake (only the small cooling ventilator for the mainboard in the upper section will keep working)
I made this for the V3 (large ventilator) but it look so nice behind the transparant grey cover that I also placed it in my V3.2


For the assembling I guess there is no explanation needed. T
