The CC2 printer’s filament is stored on the side, exposed to the open air, which makes it prone to moisture absorption. Additionally, the filament spool extends beyond the printer’s footprint, which I find aesthetically unappealing, and the feed tube at the top collides with the transparent cover.

Therefore, I conceived a design that places the filament spool on the top, maintaining the overall compact form factor by simply raising the height of the enclosure. This design leverages the existing pivot axis and can also use the printer’s chamber temperature to assist in drying the filament. Furthermore, a deflector chute can be installed on the auxiliary fan to direct airflow upward.

Components required: approximately 140 M3×8 flat-head self-tapping screws

            Drag chain cable tray (tank chain), 10×10, 1 meter long (though only about 0.5 meters will actually be used; the rest needs to be disassembled)

            Four 4×2.5 transparent gray filament feed tubes, each less than 90 cm in length—these will need to be trimmed later

            A 4-pin extension cable

The five-way connector must accommodate a large-radius bend; smaller bends will cause the filament to jam, as the feed tube cannot be folded—folding it will result in filament blockage.
