Did you 3D print this model?

3D model description

Hi everyone!
i'm uploading a copy i designed for the original anet A8 cooling fan duct, and a redesign I made to repair the nozzle from being hit by cooling air (you can see the comparison images to spot the difference).
For a long time now i have been using circular fan duct, but even at 100% fan speed the cooling air was just too diffused to have a fast filament cooling.
With this design, the colling air blow is way more concentrated. I was able to rise printing temperature and decrease fan speed (50%), still having great cooling.
Result is stronger prints (due to higher printing temperature), better overhang surfaces and no rising edges (due to more concentrated air blow), and less noise because of the lower fan speed, very happy with how that turned out.
If you are using a circular or semicircular fan duct, keep in mind that using this duct will require a higher nozzle Temperature, since cooling effect on the nozzle will however be more significant than in diffused-blow ducts.
Hope this will be useful to somebody else too!
If you like my designs you can follow me on IG, where i often post upgrades on my work!
