Filament Spool Winder

This is a spool winder for transferring filament from one spool to another. Inspired by the need to use certain filament spools for the Bambu Lab AMS. This build should speed up the process and give a nice tight winding. There is room for improvement, so feel free to give some feedback either on Printables or on the Youtube videos.

This version is 100% 3D printed (not including the mounting screws). Future versions will use bearings and possibly a motor to drive the gears.

The images show the assemblies mounted to a 2x6 for testing. The assemblies can be mounted to a similar board or to a base made from aluminum extrusions.

Printing Recommendations

I used PLA while developing the spool winder. I would recommend using PETG, or Nylon CF, or other stronger, stiffer filament.

The ‘worm’ gear can be tricky to print. In Bambu Lab Studio, I set the part upright and set support to tree (auto) and threshold angle at 10. Set a brim at 8mm.

The gears are easy to print and require no support or post processing.

The bases need some support and did well with tree (auto) and threshold angle of 30.

I used 4 walls and 15% infill on most pieces. The thumbscrews I used 100% infill.

Assembly

Most of the assembly is easy and self-explanatory.

Note that the rear driven gear is reverse threaded.
