Fan duct set (40mm) for customizable direct drive extruder

This are two fan ducts for the very nice direct extruder https://www.thingiverse.com/thing:1383913. One fan duct is for the E3D hotend and the other is for the print or layer cooling.
I remixed the hotend fan from here https://www.thingiverse.com/thing:929326
and the print fan from here https://www.thingiverse.com/thing:2175956

** Update 2018-04-16 **
I added an other fang design (v2) for a closer and sharper air stream
