This is the new, original Printrbot Spool Coaster, a portable filament stand that manages your filament while printing. The stand features 4 roller bearings to provide a smooth unrolling action. We laser cut them out of 6mm birch plywood for a sturdy construction.
Note: Laser cut wood is standard 1/4″ (6mm) thick
This item is sold as a kit. Instructions are available at Printrbot’s dozuki site
