Anet E16 fan duct

Upgraded duct for the part-cooling fan on the Anet E16. It pretty much just bolts on like the original did, only difference is that instead of having one of the screws tightened against a nut, it's designed so that it gets screwed directly to the plastic which makes it easier to install.
I included an f3d file in case you want to customize it.

Make sure that the fan duct doesn’t stick out below the nozzle! If you home the z axis there should be a few millimeters between the printer bed and the fan duct. If it's too low, you can raise it a bit by tilting the hot end housing.
