High air flow Ender 3 fan cover/guard
Description
I was looking for a better fan cover for the Ender 3 and found the design of #k19k19. Very clever to use a screw to fix the cover. However all designs I could find restrict the airflow too much. You can hear that clearly by the noise the fan makes at full speed. I created a much higher and less restrictive design with enough protection for my needs. The screw needs some optimization I have to say, but for the moment it holds alright. Print without support but keep an eye on layer height. The screw needs some detail. I recommend 0.12 mm. Infill not really needed. Enjoy!
