Prusa R3 nozzle fan fix

thingiverse

To stabilize the Prusa R3 print fan mounting, a straightforward modification can be made. The issue arises from the fact that the current setup relies solely on one screw to secure the fan assembly, making it prone to rotation. By incorporating a ridge onto the original cooling nozzle, the entire fan assembly is now fully encased at its tip. This results in the assembly remaining securely attached even with the single screw in place.
