Cuộn nhựa thay thế cho Creality CFS

Had a cardboard spool that was too small for my CFS. Looked for a good printable replacement and didn't find one that had all the things I wanted. This is based off of a Creality plastic spool's dimensions and the features I would want personally.

1. BOLD material listed on the side, updated with my commonly used materials 03/19/25.
2. Filament retainer holes evenly spaced around lip.
3. No complex patterns to make easier to print. Just lines to enforce strength and show filament amount. (I love hexagons, but form follows function here)

The screw threads are pretty beefy. Currently I suggest printing the inner piece first, then screwing it into the outer piece while still adhered to the bed.
