30mm Air Filter Fan Guard

thingiverse

Fits my 30mm fan on Monoprice perfectly. I cut a piece of 1/4" thick filter material about 30mm x 30mm to create a snug fit into the holder. The original file is included if you need to adjust the measurements. This will effectively block unwanted particles like animal hair, larger dust particles, and even pesky fruit fly debris from your banana that might otherwise be sucked in. However, I'm not liable for any issues caused by using an incorrect filter element that could stress out your fan and burn it up. FYI: If you notice a change in the pitch of your fan after installing the filter, it's likely stressing your fan. To maintain your fan properly, you may want to change or wash the filter once a week. When washing, make sure it's completely dry before reinstalling.
