Snapmaker Filament Holder for U1

The Filament Holder is a heavy-duty, low-friction spool support arm designed to mount directly onto the aluminum profile chassis frame of the Snapmaker U1. In high-speed 3D printing environments like the U1's CoreXY platform, standard unguided or shaky spool mounts can introduce sudden tugs, rotational resistance, or severe frame vibrations that degrade print surface finish and induce ghosting artifacts.
