AMS Hub holder for A1

AMS Hub Mount for Bambu Lab A1 provides a secure and stable way to attach the AMS hub directly to the printer. The mount features a locking mechanism to prevent the hub from popping out and a PTFE tube guide to reduce bending and ensure smooth filament feeding. It is designed as a two-part construction for high strength and easy, support-free 3D printing.

The mount follows the exact radius of the printer’s rear frame, creating a clean, seamless look that naturally continues the original design of the printer.

It mounts to the rear frame using M3 threaded holes with 53 mm spacing and can be installed with the original M3×8 screws from the stock spool holder.
