MakerFarm Prusa i3 Filament/Nozzle Cooler

thingiverse

This modular cooling system is designed for MakerFarm Prusa i3 printers, featuring two 40mm fans (compatible with 40x40x10 and 40x40x20 sizes). One fan cools the filament post-nozzle, while the other cools the hot end fins. Originally crafted for Metal Magma hot ends, it may also work with J-Head MK-V types due to their similar dimensions. A modified fan shroud and cooling duct are included for J-Head MK-IV compatibility too. For Metal Magma or J-Head MK-V usage, print parts starting with "Magma." For J-Head MK-IV users, print Magma_Hot_End_Cooler_Mount.STL, Magma_Hot_End_Cooler_Revised.STL, Fan_Shroud_Left.STL, and Filament_Cooler.STL. The latter two accommodate the J-Head MK-IV's taller height. Attach fans with #4 machine screws, and mounts with #6 machine screws to cooling ducts.
