FanDuct Ender-4

I wanted to use a 40mm fan for a fanduct on my ender 4.
So I took the fanduct from "ninne" for the ender 2 and changed the design for the ender 4.

I used the "PAPST 414" as fan but it should work with every 40mm fan.
I recommend a 24v fan because you could easily plug the fan into fanport 1 and control him per software.

You need Support for both parts, but one part has support for the "ear" included.

It works good, but now I have problems with warping :D.
