A fan guard (for the inlet side) with anti-backwash blades for 30mm fans. Helps prevent air spilling where it shouldn't.
The small size makes it a bit fiddly to print, but even quite rough prints seem to work very effectively. I printed it with 0.45mm width and 0.16mm layers. The holes take a #4-20 flat head thread rolling screw (or similar).
I use these for the fan on the extruder heat break with these fans
