The filamentalist rewinder is an awesome alternative to a filament buffer. It uses the filament itself to drive a roller that then rewinds the filament back onto the spool. The design also includes a pre-gate sensor option that uses Omron D2F-3L switches (simulated roller), which I had a lot of trouble trying to get filament through. It would frequently jam, unless I had a formed tip (i.e. one that tapers to a point).
I needed a method that didn't care what the end of the filament looked like!
In addition to the original BOM, you will need 5.556 mm ball bearings. Oddly specific, but it seems to be a common size - and I had some from my extruder sensor.
