FILAMENT SPOOL REWINDER

This spool rewinder is designed to support my Auto Filament Splicer. When the process starts rewinding merged filaments (e.g. up to 50m) the printer pulls the merged filament out of the PTFE tube and the extruder. This joined filament must be collected on one spool either manually or using this rewinder. The rewinder is a soft rewinder, meaning it does not hard pull the filament but forces the spool holder to turn backward, so as the spool. In this respect, it starts collecting the excess filament onto the main spool. You can also use it for other purposes such as transferring filaments from one spool to another or while using my Automatic Filament Change project.
