A classic extruder, practical with low hardware requirements. Ideal for people with uncomplicated needs.

Highly similar to many other designs found here on Thingiverse. Don't get me wrong, its still good but lacks much (read any) differentiation from similar designs.

One thing I would have like to have seen is the two halves of the case "keyed" together. As it stands, only the bolts keep the two halves in true.

Nice Extruder. :)
It is exactly that what i searched for, but can you pls remake this with a 3mm Version and maybe a acess for a Pushfit-Connector?

Very nice design! Can you share the CAD file in STEP format so I can remix it with Rhino? I need to use a different bowden connector than the E3D one. Many thanks!

First, thanks for sharing your great feeder. The design is solid and straight forward.

I have two questions:
Is this for 3mm filament? Because the holes are too small.
And would it be possible to make the feeder for the normal UM2 fitting?


Thanks for your interest.

  1. It is for 1.75mm only.

  2. I do not know about UM2 fitting dimensions. Fitting used in this design is the one from E3Dv6 hotend.

Thank you.

Can you please post the solidworks files? i would like to update it to use a standard pfte fitting

I uploaded solidworks files.
I expect you make better design for others.

Nice disegn!
If I had the bearing 608 instead of 688 ... how can I adapt the model ?

Thank you

I'm sorry 608 bearing can not be used, I have to change everything to make it fit into this model.
