If you print directly from a dry box that fits into the side pocket of the Core One/+, you'll need a place to store the detachable part of the spool holder. This model will do that for you :)

This model won't work with the Core One L, as it attaches with magnets

Materials & Print Settings

You'll need 4x Ø10mm x 3mm magnets. You can probably get away with just using 2, if you use strong magnets.

The magnets should fit snugly without the need for glue. But have some at hand, just in case.

Print Settings

This model prints without support and should be printed upside down.
I printed mine in PETG, but PLA should work just fine.
