40mm Fan Guard

thingiverse

I finally escaped the frustration of continually damaging my extruder fan on my trusty Prusa i3 by installing a guard. Now, I carefully position it so that the smaller hole faces away from the fan, allowing for unobstructed airflow and preventing debris from causing further harm to those delicate blades. A screwdriver or Allen wrench is powerless to reach them, even with a bit of force applied.
