About this 3D model

Eryone Center Ring 76mm with pin This is for the Original Universal Spool Adapter and fits eryone cardboard spools I printed the Universal Spool Adapter from Humebeam. Since the cardboard spools from Eryone are not of great quality, I remixed the fitting 76mm center ring and added a small pin. The pin snugly fits into the original spool cutouts and prevents the cardboard core from rotating. I ripped my cardboard spools and replaced them with the universal adapter for use in original AMS. Please assemble the center ring as shown in the fourth photo.
