A1 Mini Spool Holder Anti-Fall Guard

When the spool gets light near the end, it can easily get pulled off-center or sit unevenly on the A1 mini’s holder – and in rare cases, even fall off. This elegant snap-on guard adds a subtle lip that helps keep the spool aligned and secure. It installs in seconds, requires no tools, and doesn’t interfere with loading or rotation. A clean, practical upgrade for smoother prints.
