MK3 dual fan

thingiverse

I created my own version because the original remix had some issues slicing for me. This mod for the MK3 enables dual blower fans on the hot-end, resulting in improved cooling. To accomplish this electrically, you can split the power and ground wires from the existing fan and connect them to the new fan. This approach works well, requires minimal modifications, and significantly enhances cooling performance. Print with polycarbonate to prevent drooping when printing high-temperature plastics like ABS.
