E3D V6 - 40mm fan duct

thingiverse

I'm upgrading my 30mm fan with a 40x10mm fan, requiring a new fan duct to fit the larger model. The fan ducts I found were slightly too big, so I created a custom-made one. When installing this setup, be cautious of the heatbreak as it won't stretch much. To avoid any issues, print the heatbreak vertically.
