40mm Fan Guard (turbine style, no screws)

thingiverse

I know there's a multitude of these designs available on Thingiverse, but I wanted to create my own version. Some fan guards seem to obstruct airflow excessively, so I designed this alternative. This design doesn't require any screws, instead, it simply snaps into the mounting holes already present on a 40mm fan. Edit: If you find that the small pegs are too loose, try securing them with an oversized piece of duct tape or electrical tape and pressing it firmly in place.
