I needed a spool holder that wouldn't strain the extruder motor of my A20. the original spool holder is too small for the E-Sun spools (which have a 56 mm diameter hole) and made the filament advance in jerks. I therefore created an accessory that is inserted into the hole in the original support and regularly rotates the reel on its axis.
