I've printed the duct and the extruder for 1.75mm with bracket, for my new E3D v6. To be installed on QU-BD 2Up.
I have the bearing and bolt you specified. I'll get the M4 bolt and nut.
From the drawing, I cannot tell how to assemble everything. Could you provide some more detailed instructions or at least some photos/drawings to show how things fit together and in what order? Thanks.

Sorry you are having trouble with this. Because this extruder is a variation on another design and I've never printed this, I refer you to:


There are several photos of the assembled extruders. From these you can see where to put the idler bearing, M3 screw, and shoulder bolt. I think where the nuts go is pretty self evident based on the shape of the openings. If you need more help, let me know.

What is the difference between the 4 different extruders? Is the duct required? My E3D kit came with fan, etc.

There are two types of extruders. One has a bracket mounted on the side. Unfortunately the angle that is presented in the preview hides this. The other type does not have a bracket mounted on the side. If you want to use my duct with a NEMA-17 direct mount, you will have to use the extruder with the bracket. That gives the duct something to mount to.

I'd say that my duct is not required to print something. But if you want the best results, I find that its important to have a duct that cools the filament rapidly upon extrusion. It minimizes warping and delamination and enables bridging. Of my duct designs, this one lasts the longest and seems to handle bridging well.

I also posted a 1.75 and 3.0 mm version of the extruder for different diameter filament. I think they are named 2.0 and 3.0, respectively.

I hope this helps, don't hesitate to ask if you have any further questions.

Wonderfull! This design fits perfectly, and filament seems to run very smoothly. I'll be testing out a full print with it in the next couple of days - can't wait to test my bridging and overhangs with this fan shroud.
Sadly on my H-Bot design printer I lose almost 40mm of x-travel, but that makes very little difference to most of the parts I print anyway.

Thanks again for this awesome work.

Its my pleasure. I'm glad this adaptation worked so well. Thank you for keeping me updated. Since I didn't actually have your extruder setup I had to kind of "wing it" based on your drawings. Its great when these things work out.
