Bambu A1 mini dual spool holder

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.

⚠ Note on Weight & Balance
Inertia from a fast-moving print bed can affect stability when fully loaded. If you are printing at high speeds with three full 1kg spools, you may notice the front edge of the printer lifting slightly during rapid Y-axis movements.

I recommend using two full spools or a combination of partial rolls. If you must use three full spools, consider lowering your travel acceleration or securing the printer base.
