About this 3D model

Version 4 seems to fit just fine now after some adjustments also I originally had this installed backwards on my TOM MK7! Installed the correct way makes it line up with the hot end much better. I liked the MK8 version so I modified it to fit my MK7 Thing-O-Matic. I've also added air holes on the sides because my filament was getting too hot and bending and binding before it could get down the the extruder heater. I just uploaded v4 which moves the ducts closer to the print head and probably uses less plastic to print too.
