2024/5/18 UPDATE: Uploaded v2 that directs more air, and closer to the nozzle. v2 should print more easily too. Latest version of my models are on github, I only remember to update printables occasionally. Latest model will be at https://github.com/aaronse/v1engineering-mods/tree/main/mp3dp-v4/mods/biqu-h2-fan-duct. Uploaded some images showing v1 versus v2 of the duct. Hope that helps, cheers!
Get a good fan. This fan duct seems to work… But I noted some potential improvements… https://forum.v1e.com/t/mp3dp-v4-azas-build/37251/290?u=azab2c
Printed 0.6mm nozzle, 0.32mm layer height. 0.2mm would be better, especially for the grub screw threads.

Created this after not finding what I wanted :
Looked at various Fan Duct models and other parts. Related V1E Forum topic at https://forum.v1e.com/t/mp3dp-repeat-h2-build/32485/17?u=azab2c
There’s a bunch on Printables, wading through those options. BTT have one on GitHub too, H2 V2s Revo >> H2 V2S Revo 4020 fan duct.STL 1.
List of models I looked at, and incorporated some ideas from. See my MP3DP v4 collection https://www.printables.com/@AzaB2C/collections/492494 for links to these and other related parts :
