After designing the rotating fan cover for the Aux fan, here is the rotating fan cover for the print head. The blades simply rotate moved by the air sucked in by the cooling fan, the speed is not high but the large number of blades makes it look like a jet engine!
Assembly instructions:
Insert the propeller into the pin found on the external frame and secure it using the central clip. When inserting the clip, press simultaneously on the center of the frame and the center of the clip, so as not to bend the three supports. If this happens, you will have to straighten them to prevent them from touching the cooling fan.
