MBI should also make upgrades for REP 1 users, well in the meantime this works fine.

Modded to use binder clips, tested it for 2 weeks and has been working very well, much better than the MBI's design.

Currently looking for springs to make aluminium parts.


  1. Print with 100% fill.
  2. cut the support for the bearings.
  3. use a m3 cap screw to secure the 623 bearings.
  4. add binder clips to the parts.
  5. replace the original MBI part.

Thanks it works.
You from .sg ?

I love the minimalist design. You can build the "spring" into the design of the arm to make it even more minimal. Just thin the arm out enough that it will give just the right amount.

A slot for a nut in the arm would allow a screw tension adjustment.

If you post a .step file I can run it through a stress analysis program to see what shapes would give a decent spring rate using ABS.

This extruder design looks like just what I need. But you uploaded the .gcode files instead of the .stl files for the bottom parts. Would you mind uploading the STLs?
