FlashForge Creator 4 - Improved 5015 Blower Air Duct for HT Extruder

This is an improved air duct for the HT extruder of the FlashForge Creator 4, but should fit other extruder types of the same printer as well. It includes two models, one for the right and one for the left extruder. It is a drop in replacement for the existing air duct but takes a 5015 blower instead of the small 4010 used originally. 

Please note that you have to remove the two spring screws holding the magnetic sheet on the print bed, as these collide with the toolhead if you don't - however i had no problems printing without these screws as the magnets holding the sheet are strong enough. The air duct attaches using the same screws as the standard one so nothing else is required. 

How to print

I printed using PAHT-CF and there are two models attached, one consisting of two parts which you have to glue together which you can print with normal supports and one you can print assembled but you need to use soluble supports. 

Please feel free to improve!
