Brad, would it be possible to get a 3mm version that works with the E3D hotend?

Yes... but slammed with Mini Kossel BETA Kits currently. It may be a week or two... Brad

Hey Brad, Any updates on the 3mm E3D version?

Added a 3mm E3D version

Added a 3mm E3D version to the very compact Micro Extruder design. http://www.thingiverse.com/thing:266711http://www.thingiverse.com/thi.... I have moved away from this bulkier design for now.

No problem. If you're willing to post a scad file here I'd be more than willing to do the work on my own.

SCAD is a problem as we model in Alibre PE. You can download the trial and make the mods. The source is posted here. - Brad

note: this does not center the filament hole as Johanns modified version. If you use this you will need to modify it so the hole is centered. or modify your mount so that the filament hole is in the center.

Added 2 versions where the mount holes are centered on the filament hole.

Also, how does this compare to Johann's extruder?


PG35L extruder for Kossel
by Johann

This extruder is very different from my V5 extruder in that the J-Head and extruder body are mounted below the effector. Johann's remix of my V5 design has the extruder body mounted above the effector. This version was a customer requested remix. See comments below... - Brad

How does this differ from your last one?
Is this for the short shaft or long shaft PG35L?

This design like V5 works with both long and short shaft PG35L motors. There are 2 versions uploaded, one for 3mm and the other for 1.75mm.
Other differences are the J-Head is centered, the body is trimmed down, and the snap-in slot is 180 degrees opposite the mount side. Thanks for looking at my design. - Brad
