*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!
Printer:
Artillery Hornet
Rafts:
No
Supports:
Yes
Resolution:
0.2
Infill:
20
Filament:
Polyterra PLA PLASunrise Orange
Notes:
For lesser supports, bad-looking:
Print face down
**For better look, but more supports:**
Print face up
Don't print supports in the small ducts just before the nozzle, it's a pain to remove.
