I remixed this fan shroud from two different designs. One was a universal set of fan silencers, but it was designed to screw on. The other was from a design for the ender 3 that clips on the hot end shroud.
This is a fan shroud that helps protect the ender hotend fan from getting strings and particles in it. It has the added benefit of helping silence the fan as well. I was skeptical at first but it truly does make an audible difference.

I can't find the other file where I found the mounting section of the fan. Thingaverse needs an update badly.
I printed it with the round part of the fan facing down with supports. Its printed with PLA.
