Anet A8 E3D Duct fan for Anet_a8_e3d_v6_bowden_print_carriage_redux

1. I didn't want the wiring for my extruder out the side like the original design, so it needed to be wider.
2. The original design didn't extend far enough to the back of the machine.
3. The throat of the duct was too small for the aftermarket fan I installed (approx. 1mm x 1mm wider).
4. The throat of the duct was too thin for my liking, especially after snapping at least three prints trying to install it.
