92mm fan duct

thingiverse

I'm expecting some new hardware soon, including a Dan Case A4 and a Noctual NH-L9, which I've been reading can be greatly improved with a fan duct. The only pre-made option I could find was a 3D print, but it didn't quite meet my expectations, so I quickly whipped up this design in Tinkercad - it's not the prettiest thing, but hopefully, it'll get the job done when my parts arrive. I'd be more than happy for others to take a look and improve on my creation.
