I needed an adapter that would fit from cardboard cartridges from ROSA3D, in order to print with AMS.
Unfortunately, all the projects I found were either too big, too small, or ones where the roll rolls over the printed adapter.
The model has curved ridges to better grip the cardboard center of the spool, and has a cutout for the Bambu Lab wedge in the spool.
I suggest printing it with at least PETG to have the ability to dry the spool above 60C.
Print instructions:
2-3 walls
4 top/bottom layers
15% GYROID infill
