MODEL DESCRIPTION

The one spool ring to rule them all!

Bambu Lab doesn't recommend using filaments with cardboard spools with the AMS, as they can produce dust and block the rollers or the cardboard edges could fray, causing issues. By snapping this model onto the cardboard spools, only plastic makes contact with the AMS, solving these issues.

If you find this works with a brand of filament with cardboard spools that's not listed here, please leave a make or a comment and I will add it to the list!

Printing instructions

I recommend you to print the regular cardboard_spool_ring file first and make sure the diameter is exactly 202 mm. If it doesn't fit in your AMS or you have other issues, look at the Versions / Troubleshooting chapter below. You can also have a look at the makes and see if someone else used the same filament as you and used any special parameters to make it work.

Prints nicely without supports in PLA at 0.20 mm layer height. I provided the STL (to use in your favorite slicer) as well as the Fusion 360 design file, should you need to make changes for a filament brand with a different spool size or hole pattern. I also provided two “.gcode.3mf” files (one for Bambu Basic PLA, one for Generic PLA) which you can directly put on a microSD card, insert it into your Bambu Lab X1C and print from the touchscreen. If your printer is not dimensionally accurate you may have to scale the print down / up. If you're using a Bambu Lab X1C to print this on the Cool Plate, make sure to only apply a very light amount of glue stick, else it may be difficult to remove it from the plate without breaking it. If you have one, I would highly recommend printing it on a textured PEI sheet without glue stick, which makes it very easy to remove the print without damage.

Versions / Troubleshooting

As the size of each AMS and cardboard spool is slightly different, you may need to print a different version in order to make it work. Look through the following steps and try them in order until your problem is solved.

• If the AMS doesn't close, try printing cardboard_spool_ring-thinner
• If the edges of the cardboard spool are uneven or wobbly (as was reported by some users with Overture spools), try printing cardboard_spool_ring-thinner_straight
  • As this version doesn't have a snap on the side, you need to glue it to the spool, either by using CA glue or applying some glue stick on the side.
• If the printed ring only fits very loosely on the spool and falls off, try printing cardboard_spool_ring-smaller
• If the cardboard spool spins on the printed ring, apply a touch of glue stick to the ring.
• If the cardboard spool and spool rings slip in the AMS, try reprinting the rings using the "fuzzy" setting in Bambu Studio set to 0.2/0.2
