*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.

Intro

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).

Disclaimer

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!

Needed parts

  • 2x 24V radial fans 50x50x15
  • 4x M4 screws and nuts, for fixing the fans: 20mm works but is a little too short, 22mm should be perfect
  • (*optional*) a crimping tool for JST-XH, plus pins and housing, to shorten the fan cables.

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