FlexFit Spool Silica box

FlexFit Spool Silica Box FlexFit Spool Silica Box is a truly universal desiccant container designed to fit inside many different filament spools.Most spool silica boxes only fit a limited range of hub diameters or spool widths. This design solves both problems with independent threaded adjustment, allowing the box to adapt to different spool cores while staying centered and secure. AirflowAnother key advantage is airflow. Even when installed tightly, the box does not block the spool core completely. A gap remains between the spool walls and the container, helping air move through the perforations and around the silica gel for faster moisture exchange.
