Drop in replacement for my MK6+ 3mm extruder using 608 bearing instead of Delrin plunger.


I know, Sooo last year darling...

There are several of these already, but I couldn't find one without springs, gears, etc.

If this is a duplicate, please let me know in the comments and I'll happily make it a derivative.

My MK6+ still has a fair bit of 3mm filament to work through and it finally gave up extruding.

I taped it up and managed to print this replacement, phew.

This is for anyone in the same boat.

could you please upload one thing for 1.75mm?
I have bis issues with the bearing and yours would be perfect, bu I need it for 1.75mm fillament

I know this is an older thing, but are you still using this? I've got a bunch of things I'd like to "set & forget" on my ToM and while I don't have LOTS of problems with my MK6, if this keeps the ABS flowing I'm all in. Still working as well as when you installed it? I've got a couple spools of 3mm I've got to use up before I switch heads on my ToM.

Yes, I still use it, only occasionally, but I leave ABS in it, and it remains under tension.

So you can't adjust the pressure and you're bound to one filament diameter (no 3.0, 3.1, 3.2 or 2.98mm )?

Designing a one piece extruder is neat.  Is there a way to slightly change the roller spacing?  I'm wondering about the 'sweet spot' pressure between the rollers for feeding 3mm filament.  The setting seems pretty narrow on my MK6 for feeding ABS, and I always have to adjust it slightly when changing rolls of filament and/or from ABS to PLA. 

No, I'm afraid not, you can have the original file if you want, you'll need Cubify Invent if you want to modify it?

I am going to try your extruder file as-is.  You may have hit upon something by printing an ABS extruder as one piece (compared to the more rigid plexiglas on the MK6).  There is some 'give' in ABS, and that could explain why no adjusting is needed for the tiny differences in filament diameters.

Let me know how you get on?

great work, i really appreciate your ToM-enhancements!

Thanks, I'll post it at some point !
