This is a BETA model, so feedback is welcomed in the comments. I am personally running the v2 version and it is working very well so far. With the 2510 duct from Github, I was getting some occasional clogs but not anymore.
I recommend printing it face down with a brim. You may also need to reduce your accels to prevent the print from getting knocked off the plate. And also it's best to use ABS, ASA, or PC for high-temp resistance.
Needs (4x) four M3x14 screws to attach your fan to it.
Please post your makes & comments!
Update 4/3/2025 - In the v1 file, I noticed that the area for the screw heads was not large enough, particularly if you wanted to use a washer. So I came up with version 2 which I think also has a little better air flow and smoother lines. Both versions are available in the files section.
