I noticed that the hotend fan creates a draft in the area of the nozzle when operating. With some technical materials, you really don't want a draft on the printed Model.
This cover prevents the draft.
At the same time, the guard protects against accidental damage of the fan.
The guard is designed so that the airflow is not restricted or increases its noise.
