Composite coil for filament. D=220 mm

thingiverse

Composite filament coil assembly. 220 mm in diameter. Side walls printed with 3 segments to fit on a standard table measuring 200x200 mm. The segments can be glued together if desired, but they do not have to be. A lock on the walls prevents them from coming loose. Assemble spool using 3 bolts M6x110. This design allows for different widths of yarn to be set on the bobbin. It also securely holds the filaments in place and prevents yarn from getting tangled inside the coil during unwinding.
