40mm Flush Widemouth Duct

40mm rounded fan duct with a single edge taken off to fit on printheads with particularly large part cooling fans. Standard 40mm fan bolt layout, including insets for 3m square bolt heads. I designed this specifically for my setup with the Hero Me Gen 4, but it'll work fine for most setups.

I've included a version with the full disk intake and a simple spacer that can be scaled up if needed.

I'll try to provide STEP files but these were made in fusion360 a while back.
