WIth 7 and 8 pitch wouldn’t work maybe 5 but it’s better to change 3d model. For now I’m using without the duct.

Champey design should be fine for not trimed one, maybe he can help us and make one for 160mm or maybe this one would work: Flipsky 65161 Duct by E_Roberts - Thingiverse need to test. One I printed before from this forum was Flipsky65161Duct (1).stl I think same as your’s.
