A better fan duct for prusanozzle

thingiverse

Unlike some individuals who can print without a Prusa nozzle fan, I faced challenges and received poor results when utilizing other ducts for this purpose. However, the current duct appears to be the ideal solution for achieving stable prints. In terms of fastening it, tapping the holes eliminates the need for nuts; 10mm M3 bolts are sufficient to attach the fan to my compact extruder version. I would recommend upgrading to version 3 now.
