This is a top-mounted dual spool holder designed for the Bambu Lab A1 Mini. It attaches to the Z-column using the printer's existing hardware, providing a secure and integrated setup.

The mount accommodates two standard filament spools, which allows a second color or material to be staged for use. This feature significantly reduces the time required for manual filament changes during a print. The design is non-obstructive and permits the continued use of the original factory spool holder.

The spool holder components are push-to-fit. For an especially sturdy and permanent fit, a light tap with a hammer may be required during assembly.

This is a convenience upgrade for rapid material and color changes (manual intervention required) and does not provide multi-material printing capabilities like the AMS system.
