Thing-o-Matic 40 mm Fan Guard (with access to screws)

Another fan guard for the Thing-o-Matic 40 mm fan.

This one keeps the fan blades safe from an alan key in case the fan is still running while disassembling the extruder block.

There is some space between the fan blades and the spokes of the fan guard, so the airflow isn't interrupted and it doesn't make too much noise.

Instructions

Just print and press fit on the fan, no extra materials needed.
