Dual Part Cooling Fan Mount / Shroud for Prusa i3 MK3S (Reinforced) (Extended)

thingiverse

This is a remix of the dual-fan nozzle cooler for Original Prusa i3 mk3S by ANTALIFE, which itself is a remix of the original by RosyRL. I've used the original for some time now. During that time, I discovered ANTALIFE's "reinforced" remix and truly liked the concept. However, I also recently switched to a different heat break - a Slice Engineering Copperhead. This new heat break is slightly longer than the standard Prusa E3D heat break, so at its default size, my previous nozzle cooler points at the heater block instead of below it, resulting in some problems and not functioning very well. This remix is 2mm "taller" - that is, the fan outlets are positioned 2mm further below the extruder body than the original. This adjustment makes it so it is positioned about the same place (relative to the nozzle) as the original with the OEM heat break. It's not entirely identical - I tried modifying the model directly in Blender but that became too complicated, so I ended up rebuilding it in Fusion 360. I've also included the F3D file so that if anyone else wants to make further changes, you don't have to redo everything from scratch like I did.
