CR-10 40mm fan duct

thingiverse

Thanks for junaling's awesome design! This fan duct works perfectly for me with dual Noctua 40x10mm fans, delivering very efficient cooling performance. I was a bit worried about the axial fan's ability to cool the hot end, but it actually worked really well. I personally prefer this "just enough" solution over an overkill, noisy, and ugly blower fan. Remix Note: - Choose V1 instead of V2 because its blower end is too high, and I also hate the extra cable hole for the top fan. - Added reinforce mounting holes to reduce the diameter perfectly fit original M3 screws. - Repaired the model for S3D. Highly Recommend to print in PETG/ABS. You can find a lot of 40mm fan grills to be installed. Recommendations: https://www.thingiverse.com/thing:2505568
