See if you can improve air flow coverage from the fan duct output

Air flow seems to be more heavily concentrated in the center of the duct output. Flow on the outer edges is limited and is probably not that effective.

I think there's room for improvement here.

Currently testing this version of the duct: https://github.com/djsplice/SCS/blob/ad7873f3d70ec007562186c8a3180798ded0b008/stl/Fan%20Duct.stl

I have been testing your v2 system and I have had success with correcting benchy sag, but I do not get any flow in the corners of the bed. Maybe if you reduce the duct height at the center it will reduce flow in the center and cause a more even distribution of flow to the edges of the duct.
