AC Infinity Airplate 120mm Fan Filter Adapter

I added some AC Infinity Airplate S7 fans to my server closet and I wanted a filter mesh for the intake fans. I initially tired to use cheap magnetic mesh screens (https://www.amazon.com/dp/B0BMXPMG5P) but they kept falling off. 

This adapter can work without removing the rear grill cover but it works so much better removing it. The filter adapter slides in and out for quick cleaning. The adapter is 20mm in height and flairs out to avoid hitting the sides of whatever the fans are mounted to.
