To create a spool from an old Dimension cartridge, first empty it of any remaining filament (typically 20-50m remains). Next, wind your chosen filament onto the spool, although it's unclear if this works with 3mm filament. Finally, reassemble and feed your 3D printer for a satisfying result.

The text could be enlarged for better readability; consider making a spool holder for optimal fit (49-52mm diameter required for the center hole).
