If you have a pair of M3x20mm screws around you should use this replacement fan shroud and duct instead. It replaces the whole assembly, and fits perfectly on the Anycubic Mega-Zero v1 with an MK8 end, just move the existing fans over.

For anyone else who wants to attempt this, I did have to modify the bottom of the stock metal fan shroud with a Dremel for clearance of the new block and sock.

This is a 2mm shorter version of the factory "wind nozzle" blower fan duct. I needed a quick replacement that was compatible with a Creality MK8 (Ender-5) hot end with a titanium all-metal heat break, as the creality hot end combo is slightly shorter than the factory part.

FreeCAD project is provided as well.
