Filament is wound around a cardboard core and secured with straps. This allows the reuse of the spool sides, reducing waste.

    To be fair, never had a problem with cardboard spools so far. But I also have a reusable spool from Sunlu I’m using for most of my “normal” filament where color doesn’t matter.
