How to reload your ECO Spool

    ECO refills

    Which refill do you have?

    Our refills grew from 58mm to 60mm, the Bambu Lab standard. Answer two questions and you'll have your answer and the steps to load it.

    1

    Identify your refill

    Pick one refill below. Go by the label on the box.

    2

    Identify your spool

    Pick one spool below. Open it and look at the inner face of each half.

    Does it fit?

    Optional (sold separately)Load a DRY090 Canister

    The bore through the middle of the spool takes a DRY090 Canister, held at each end by a clip. It is sized for the canister and nothing else — never pour loose desiccant, sachets or refill granules in there. They migrate into the coil and jam the feed.
