Alfawise U30 Pro - 40mm Fan Duct

thingiverse

I designed a custom 40mm Fan Duct for my Alfawise U30 (Pro) printer, with the flexibility to replace all components individually. I opted for one 12V Noctua fan in front of the hotend, measuring 40x10 mm, and two 12V Noctua fans for part cooling, each measuring 40x20 mm. To assemble it, you can use the original M3 screws. For a standalone base, simply mount the fan on the opposite side, similar to the stock Fan Duct. I've updated the design twice: first, I created a separate base; second, I uploaded new files with thicker walls near the nozzle's air exit, ensuring optimal performance. As an added precaution, I re-uploaded all files for your convenience. You can combine this fan duct with my Radial Fan Mount, available on Thingiverse (https://www.thingiverse.com/thing:4229634).
