The file 'Adjustable Semi-Circular Anet A8 Fan Duct 3D Printer Model' is (stl) file type, size is 655.2KB.
I've noticed with the original fan duct the walls are very thin (salmon = stock fan duct)
I've added a few models (green = +1mm, white = +3mm) so you can precisely bring the fan duct as close to the print as possible (you'll thank me later)
