Bambu Lab Spool Holder Replacement for A1 / P1 / X1 Series – Filament Spool Mount
The Bambu Lab Spool Holder is the official filament spool mounting system for A1, P1, and X1 Series printers. This holder allows you to mount filament spools directly to your printer when not using an AMS or AMS Lite, providing a convenient single-spool printing solution.
Essential for replacing broken, worn, or missing spool holders to restore standalone filament feeding capability.
When to Replace
- Broken Mount – Holder snapped or cracked
