CCTree and YXPolyer spool adapters for Bambu Lab AMS multi-filament changer.

Even though these suppliers were claiming compatibility with AMS, their spools did not work well, especially when was full. So I designed this model that has a few additional reliability features over most adapters out there, such as tabs and a lip that hold the adater very securely on the spool.

Includes the parametric Fusion360 CAD model to adapt the design to other spools. Details and instructions in this post: [https://raphtronic.blogspot.com/2025/09/diy-parametric-spool-adapter-ring-for.html](https://raphtronic.blogspot.com/2025/09/diy-parametric-spool-adapter-ring-for.html)
