I made this fan duct to help direct a more focused air stream to where it's needed. I designed it to have a BLTouch and the option to design a different fanduct and not need to remove everything. Just unscrew the 2 screws and install the new ducting. This is my first fan duct design so it might be rough but it seems to work well so far on my H2. I added photos of the airpath in water to show what its doing.
Print both parts with supports. The fan duct part works well rotated around 120 degrees. Standing with the outlets pointing up. Early test print photos added to show the print orientation.
