it looks like it's missing a part.. Where do we get this? Its the one where the fan is mounted in the middle.

don't know what part you mean. all pieces necessary are there.

Hello. Your Fan Duct looks good. But when I slice it through Cura there are a lot of gaps in cover. I tried to fix it through many ways -- but with no results.
Can you say which slicer did you use for this model?

Thank you

slices fine for me in Simplify3D, Cura and slic3r. line width 0.38 to 0.40

Thank you. I tried Simplify3D -- all good :)

But one of the fans, right one, will have its intake obstructed. I think this design needs some work.

actually the left one is partially obstructed. but the airflow is still by far sufficient. anyhow this is a temporary solution i've used ages ago and have since designed a 3-wheel and mgn12 carriage so no further development will go into this. feel free to modify it to your liking though.

I have a 5015 radial blower, could you change the ,odel to fit it?
My design skills are not that great

i don't have a 5015 fan, so i can't make one that would fit.

try this instead: https://www.thingiverse.com/thing:1109880

use openscad to modify it to your needs.
