Since there’s not a ton of info out there yet, I thought it’d be helpful to put together a straightforward list of official CFS accessories — the ones that are actually useful to have on hand, whether you’re replacing worn parts or just want to be prepared.
All the items below are original Creality parts.
Some are must-haves for basic operation, while others are good spares or upgrades depending on how heavily you use your printer.
