Description
External Spool Holder for Bambu Lab P2S + AMS Pro 2
*** Updated model now includes both 74 mm and 44 mm rib spacing.
The Fusion file is also included for easy customization of rib spacing on MakerWorld—simply set the parameter to ½ of your desired rib spacing. ***
This external spool holder allows you to mount a filament spool on either side of the AMS Pro 2, giving you more flexibility when printing with materials that don’t fit the AMS or when you simply need quick access to an additional spool.
The holder slides securely between the fins on the AMS 2 Pro (Rib spacing ~74 mm). Compatibility with the original AMS has not been confirmed.
The design is made to work with the stock filament guide included with the Bambu Lab P2S, so no extra hardware is needed.
If you don’t already have a filament guide, Bambu Lab provides printable files and compatible PTFE connectors here:
