A redesign of the printed parts of the RepRap Pro Huxley extruder, to use push-to-fit type connectors on each end of the Bowden tube.

Made because we had lots of problems with the tube popping out under load from the extruder. The push-to-fit connectors are much sturdier.

Can be retrofitted to a stock Rep Rap Pro Huxley.

This is a derived work of the original Rep Rap Pro Huxley, which can be found at https://github.com/reprappro/Huxley

There is also a git repository with these changes made to the original Rep Rap Pro Huxley design, at

You may also want to look into this as a simpler alternative (I didn't know these were available when I started this project):


I've published a blog post with illustrated instructions, here:

Modified emaker huxley wade bowden connector part

Yes, indeed. I missed your design the first time around too (I must have been searching for Rep Rap Pro mods only, missed the eMaker stuff!)

So you have a 4mm push-to-fit at one end, what do you use at the other end?

Late reply, but other end has the same, push fitting into screw thread of plastic, then nut, alternativly latest design ha thread into aluminium which is bolted down.

Implementing this into my own duel head extruder for prusa :)
