Spool holder

This 3D-printed holder allows you to convert an Amazon cereal box into an airtight dry box for 3D printing filament. Assembly requires two brackets, which are securely attached to the box via approximately 3,25 mm holes using either screws or rivets. A standard round rod (wood, aluminum, something else) with a diameter of 12 mm and a length of round about 88 mm serves as the spindle. The design ensures stable support for the spool and is optimized for direct feeding to the printer.
