Abstract
A filament container for housing a spool of filament comprising a base and a lid that define an inner volume. The lid rotatably attached to the base and moveable between a closed position, wherein the inner volume is substantially sealed, and an open position, wherein the inner volume is accessible. First and second horizontal shafts are supported rotatably within the inner volume, parallel to and spaced from one another a distance, and rotatable about a respective longitudinal axis. The first and second horizontal shafts are adapted to support a spool of filament vertically within the inner volume and to allow the spool of filament to freely rotate about a horizontal axis that is parallel to and spaced from the longitudinal axis of each of the first and second horizontal shafts as filament is pulled from the spool and out of the filament container.
