Adapter designed for spools with large holes that are incompatible with AMS Lite (Sunlu, FIBER3D) MAX 73mm hole.
This adapter can securely accommodate a variety of spool sizes by incorporates numerous ribs that bends invards to change diameter of the adaptor.Side panels are intentionally omitted in the design, as the ribs are highly effective in providing ample contact with the inner spool walls, eliminating the need for additional material on the sides. This approach minimizes filament usage. No glue needed at all.
Feel free to choose any material for this adapter; I personally use PETG to enhance flexibility.
Installation is straightforward, and the adapter can be easily transferred and reused with different spools.
