Ender3/Pro/V2 Compact direct drive

***Edit 7.2.2022: new revision of the duct. Just small modification of the shape of body for easier print without supports. Brim is not necessary.
I also added cut-of pictures for imagination of the assembly - screws/nuts and so on.
Edit: Revision of lot of files for Ender3/Pro/V2, include assembly files.
Edit: I uploaded also "prototype" main body. It's for Ender3/Pro only! In this version is used thicker main wall between stepper and BMG. With this modification is nozzle in the center between duct's outlets. Unfortunately, you cannot use standard M3x35 DIN912 screws used for connection stepper and BMG. You have to use M3x40 and cut them little bit. That is main reason, why is this modification marked as a prototype.
Above mentioned changes are minor for current users. No need to reprint it.***

You need for assembly following fasteners (type is up to you):
2x M3x8 for assembly front part together with main body (mounting diagonally)
2x M3x8 + 2 washers DIN125 for mounting ma
