Combined two designs from Profab for their upgraded fan to allow it to be used without the shroud. I printed it as a quick test in no name black PLA and covered the back of the part that touches the heatsink in kapton tape as a precaution. It has worked so well I never bothered printing it in a higher temp resistant material. Have had zero problems with it deforming. Have not experienced any heat creep within the hot end and can definitely feel and see the difference in airflow. Overall nice upgrade without having to slap a larger fan on it so far.
Two files uploaded. One is default orientation as it will be on the machine and the other is approx the angle I had it when I printed it to minimize the supports I would need.
