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.
Identify your refill
Pick one refill below. Go by the label on the box.
Identify your spool
Pick one spool below. Open it and look at the inner face of each half.
That one isn't ours.
A Bambu Lab reusable spool has no A-side or B-side and no ring groove — it is a different design.
Can't tell? Compare the spool halves.

Does it fit?
Load it
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.
DRY090 CanistersCan't tell what you have?
Send us a photo of the box and the open spool and we'll tell you which is which. If you need the taller 2.1 B-side, it's free.
Upgrade your ECO Spool 2 to a 2.1
The 2.1 B-side is 2mm taller and has a groove for the cardboard ring. Three ways to get one — the swap and the mail-out are free.
Swap in-store — free
Bring your spools to MATERIALISATIONLAB001 — Shop 1, Ground Floor, 67–69 Regent St, Chippendale NSW — and we'll swap the B-side over on the spot.
Please quote your original order number when requesting a free swap or mail-out — we use it to confirm your ECO Spool purchase.
