11.2 Filament handling

Always store unused filament in a dry and clean environment (PLA should be stored at room temperature). Always put the tip of an unused filament through the hole on the side of a spool, to prevent it from tangling (see picture). Before the first use of the filament, verify that the string does not overlap to the side - it could jam the spool on a filament holder during print. If the string overlaps, cut it with cutting pliers.
