Print Cooling Fan Shroud Mount for mk8 Extruder

thingiverse

I wanted to upgrade my inexpensive, Chinese-made Prusa i3 with an MK8 extruder and a basic hot end by adding a print cooling fan. A suitable fan shroud caught my eye and garnered remix credit for its design. This mounting system enables the fan and shroud to attach to the extruder in place of the heat sink fan spacers that came with the machine, allowing enough clearance between the extruder, the print, and the fan shroud. The setup centers the shroud close to the nozzle, which is perfect for my requirements. I printed this part using PLA material with support structures and at an extremely slow speed because my printer was performing poorly on overhangs when operating at higher speeds. I'm now just waiting for the China Post delivery of my fan to arrive. Hopefully, it will successfully upgrade my printer's performance.
