After fitting an E3D V6 to my printer, I noticed that the fan on the E3D V6 "slung" a lot of air down onto the part being printed. I also managed to slice my finger open on the running fan, so I decided to kill two birds... This duct allows the air to enter straight into the fan and not get thrown off to the side. It also keeps fingers out.
