40mm Fan Guard (turbine style, no screws)

thingiverse

I know there's a *million* of these on Thingiverse but I wanted to make my own. Some of the other fan guards seem to restrict airflow too much, so I made this. This doesn't require any screws, and should just snap into the mounting holes already on a 40mm fan. *Edit:* If you find that the little pegs are too loose, put an oversized piece of duct tape or electrical tape and press it on and that should shim it.
