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
- width up to 90mm
- hub diameter between 50mm and 75mm
The stand included in this design supports three different rewind mechanisms:
- Gear and vertical track linear counterweight mechanism (included in this thing)
- Universal spring rewind hubs designed by Vincent Groenhuis
- Martin Hoffman's rewind arm mechanism
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)
This design was inspired by the earlier work of Vincent Groenhuis and Martin Hoffmann.
