Prusa i3 mk2s fanduct like mk3

I was redesigned old mk2s fanduct to new one. Inspiration is on mk3 fanduct. I tryed more versions but this last have best airflow. For easy assembly you must print new extruder cover. If you dont like print new cover you can cut 2 parts from old cover and put fanduct on it(see on photo cut line)
Use abs or petg to print this parts for good temperature ressistance..
If you have any questions or ideas please leave comment :)
