After several failed attempts, I finally came up with a dust prevention solution that is functional, easy to install and easy to maintain. The dust collection material is held in place merely by snapping together the two pieces of the shield.
This was designed to be mounted on rear of the fan but it could easily be mounted on the front. I personally like the look of the exposed fans but it might not be the best solution if your PC easily reachable by children or pets.
The design is fairly simple. The larger peice is the same dimensions as a 120mm PC fan and has a 3mm high lip that holds the smaller peice in place. The smaller peice snaps into the larger peice and creates a flush surface.
To install the dust collection material (screen) you just place it on top of the larger peice and snap the smaller peice into place. The choice of material is up to you. The screen that I use is designed to stop pollen and allergens. The perforations in the screen are much smaller than a traditional window screen. You can purchase this material by the roll on Amazon.
Cutting off the excess screen material is extremely easy. I just pressed the screen material up against the 3D printed edge and ran an exacto knife down each side. I cut this out in about 30 seconds. If I had taken more time I could have acheived a much closer cut.
This isn't a perfect solution for everyone due to the fact that it mounts on the back of the fan. I'll be working on a front mounted solution over the next few weeks. If you're interested in watching this project progress, just Follow it with the button below.
