Prusa MK3S alternative fan shroud

thingiverse

This is just an other alternative shroud modification to have more cooling air flow on the far side of the extruder for the R4 extruder on the MK3S. The model of the original shroud was cut of the arms and replaced with long arms. A deflector was placed at the input. Print it with ABS or more heat resistant material. Inspiration came from https://www.thingiverse.com/thing:3063554 what I was using on the R3 extruder and was very satisfied with it. This design is not "clean", there are some small rest parts inside from the original shroud what may disturb the airflow. May be I will take the time in the futrure to cleanup the desing.
