Spool adapter/protector for all Polymaker (inc PolyTerra & Polylite), Overture and Inland cardboard spools. Perfect for the Bambu Lab AMS and AMS-Lite.

My original adapter based on the Polymaker version works fantastically with polymaker and overture spools and the AMS but had some limitations. Namely, it had trouble fitting on the AMS Lite due to the inner lip and its rigidty came at the cost of its thickness.

This redesigned version corrects all these issues and provides an even better fit with the cardboard spools. And unlike the super-thin edge-only adapters available elsewhere, this makes use of the oval-sphaped hole to provide a strong connection that wont slide around or slip off while in use.

Notable features include:

• Snug fit with all overture/polymaker spools (tested personally with multiple variations).
• Better opening placement of the edge holes
• Thin edge profile, making it a much better fit for the original AMS (without needing any conversions)
• Thin face profile, making the spools less bulky and also reducing filament usage and print time
• Enhanced edge clips which reduce damage to the spool edges compared to the orginal version
• Makes use of the oval hole to privode a strong fit while in use, while also allowing easy removal

Printing

Prints equally well in PLA and PETG. PETG is recommended to enhance its longetivity (due to better layer adhesion).
