Qidi I-fast Improved Extruder-1 cooling fan shroud

Existing Extruder 1 (on the left) has a fan shroud that blows to the left of the Extruder or is vectored towards the nozzle due to the Centrifugal fan which exits from the left, but Airflow is ambiguous and not as clean as Extruder 2 which blows direction to and central to the nozzle tip.  Distance from the shroud opening to the nozzle tip of Extruder 1 is varied and not directional.   Cooling airflow is likely off axis or not centered over part resulting in poor cooling depending upon direction of print whether going clockwise or counterclockwise.

My part replaces The shroud on Extruder 1 and squares up the air flow centrally aligned to the nozzle and also squares up the distance from the shroud opening to the nozzle tip like Nozzle 2.  Shroud taper is increased and varied to keep the same Z distance from the printed part.    Airflow is more focused and directed straight to the nozzle which will improve part finish whether going clockwise or counterclockwise.
