I decided to make a metal cooling duct made from steel to direct the airflow directly on the nozzle and prevent deformation due to heat. My idea is that the fan could possibly reduce leaking from nozzle during standby, it's lighter, smaller and looks better. Thoughts, suggestions and ideas to improve the design are welcome. How does directing the airflow in such a manner affect the print? layer adhesion? warping? The metal is cut using a laser from 0.15mm carbon steel and then folded like origami. I have attached the AI vector file, but you will need a fiber laser powerful enough to cut through the material of your choice.
