Summary

A compact and reliable filament rewinder based on a linear counterweight mechanism that can be produced in a single 11 hour print.

Provides a complete filament management solution eliminating the need for the space wasting and difficult to load filament buffer.

Offers many PTFE attachment options supporting a wide range of spool, MMU, and printer configurations.

This rewinder supports filament spools with the following dimensions:

  • diameter up to 235mm (up to 300mm with this larger stand)
  • width up to 90mm
  • hub diameter between 50mm and 75mm

The stand included in this design supports three different rewind mechanisms:

My hope is that one stand which supports three rewind mechanisms will encourage more people to print and test a rewind solution as part of their MMU deployment.

The only non-printed parts required are:

  • three 608 bearings
  • a counterweight (a 0.5" or 12mm bolt and nuts are commonly used)

The linear rewind mechanism now has two additional stand options:

  • There is a drybox for moisture sensitive filaments.
  • User gcode22 released a very nice wall mounted stand.
