Description
*Update 21/02/2022* : I improved the strength of some weak parts of the duct. I also designed two small tools to help tighten the nuts holding the fans.
I really like my Artillery Hornet, as it is my first 3D printer ; however, the fans on the Artillery Hornet are quite weak, and the default duct does not a good job at directing the air flow where it should.
This gave me some poor results with overhangs and bridges (see the blue part in the
pictures).
I first found the zephirisack's fan duct, which gave better results, but it wasn't perfect: I decided to give it a try with bigger fans, radial 50x50x15, and designed this fan duct.
I was inspired by the default fan duct look (as much as I could, as those fans are bigger and shouldn't touch the spool on the right of the printer), and some parts of zephirisack's design helped me.
I was stunned by the difference good cooling can make (see orange part in the pictures).
I am not a professional in 3D design, so it's possible there are issues with this item: until now, I didn't had any. Please be cautious anyway if you use this fan duct, the fact that other people may use it kinda stress me, I cannot be held responsible in case of trouble.
If you have tips, suggestions or remarks, please share them in the comments, thanks for your indulgence!

Don't print supports in the small ducts just before the nozzle, it's a pain to remove.
