Anycubic Kobra Neo Fan Duct

thingiverse

UPDATE (2023_08_29): noticed that the duct was pointing downward a little because of some interference with the hotend fan. I opened up the side cutaway so it will fit better There didn't seem to be a lot of printable ducts on thingiverse so I thought I'd take a stab at modifying one. Originally i started remixing something from another site but after some testing, I had to scrap it and build it from scratch. I wanted to concentrate the air flow at the tips, and evenly split it. i also made sure the flow was directly onto and below the printing nozzle. Finally, I made sure that the duct slowly tapers down to maintain or increase airflow The stock heatbreak is 24.6mm long. If you are upgrading to an all-metal (bi-metal), I found one on aliexpress that is 24mm long that doesn't require changing the height of the duct. https://www.aliexpress.us/item/3256803255102947.html But if you do need one that is 2-2.5mm lower, let me know and I can make the change. I think the most common heatbreak sub is from the creality cr10, and that one is 27.5mm long. I'll post pictures once it's done printing. It's a "work in progress" once it's printed, mounted, and tested on the Kobra Neo.
