Print Profile(1)
Bill of Materials
Description
This is a low-friction spool holder specifically made for the new one-piece version of the Bambu Lab A1 spool holder, introduced in late 2024. It uses ball bearings to reduce drag and is optimized for flexible filament printing, such as TPU.
Unlike many other designs, this version ensures proper clearance around the bearings to avoid friction against the housing or roller. The result is smooth, unrestricted spool movement and improved extrusion consistency—especially useful when working with soft materials.
