I've been able to take the STL and import into SketchUp for modifications and cleanup.
Unfortunately, for the kind of work I intend to do, it is far more easier and accurate to design in context of cad part and assembly.
Thanks kcchen

I've ordered an other PTEF tube and wondering if I'll build another unit.
I've already spend too much time on this. Desperate. :oops: :? :( hElP!

There is another variant. Takes a bit of parts though.

Very interesting design. Thank you. I keep it as my last chance.
I think the Flexystruder may be a bit simpler design and just need a couple to tweaks to work.
I will post my modified design once finished.

Wish I could help, but I build mine from scratch and have had no problems. :oops:

Retraction and everything works fine, and no jams yet! 'Knock on wooden head' for luck.

I think it's a matter of precision in the opening of the PTFE tube. Mine is just so...!
Can you tell me if your tube is like mine?
What are setups? I'm trying to print big parts, and it's always jamming after 30 minutes.

Thanks Kmanley57!

My PTFE tube does not even look close to the one in your picture.

Can you send me a photo? I will machine it...

I am unwilling to take mine apart just to take a picture. But yours looks like the tube moved around when they drilled out the hobb bolt section. It should be a nice semicircle cut just like the picture in the OHAI guide shows.

FreeCAD files also available in addition to STLs...

Yes!!!
Spend my Sunday on it, but it works! It's printing for hours now... Hope it will for all of my parts.
- Tighter tolerances around shaft and housing as well as around the ball bearings. This is really improving quality IMUO. No more shaking.
- PRECISE cut at shaft diameter on the TPFE tube. I'm using a 3/16 in tube from an older machine.
- Spacing between the main gear wheel and the housing is adjusted.
- Opening on the right side of the tube is now closed with a removable piece. This should allow maintenance in case of filament overflow.
- Addition of viewing openings on the tube. Dark material can be monitored if in.
- Reduction of overall complexity and radius added for improved stiffness. I'm still questioning about the slight curve on the top.
- Detail added for removing the ball bearings.
- Include are my STL files. Still need some tweaks but usable.
Lulzbot this was not cool. But still love my machine. Thank you. ;)-
This make my day! Mean all sunny my weekend... Cheer!

And for the community, the original TPFE diameter tube version.
Good night! ;)
