Spiral Grill for fan I got from amazon.

My original post is one prusaprints.

This fan cover has some depth and a spiral pattern both will help reduce noise often associated with fan grills. There are two version, this one for the amazon fan and one for the creality fan that came with my ender three. There is also a freeCAD file on the OG post that has a spreadsheet where you can edit the peg diameter and length to customize it for any 4040 fan that has two free holes.

**To install **You take out two screw, top right and bottom left, then press it on.
