Prusa I3 MK3S - Cooling Rambo

thingiverse

If, like me, you're enthusiastic about unnecessary coolings ;-) and you also have an old 92.5mm fan that's been collecting dust so you're on the right design! Even if Prusa claims that the cooling of the motherboard is pointless, I think to myself that it costs nothing to try to extend its lifespan. Especially since the space for cables in the box is quite limited and, at home, it's a total mess. Tips: Since the cover doesn't completely cover the ventilation grid of the motherboard, the airflow is drawn out by the same grid and also contributes to cooling the motor of the X axis. Finally, for information, the fan is powered by an old PC power supply with a separate ATX / 20 pins card all plugged into a wifi power outlet.
