Filament spool bearing with one way clutch 52-57, 72-74mm

This is a filament spool bearing. In fact, it is an adapter for fixing the one way clutch.

By attaching the bearing to the spool, the filament feeding is smoothed to prevent the step out, but if the rotation is too smooth, the spool may rotate in reverse due to the retraction of the filament during printing, and the filament may get caught. . To prevent this, use a one-way clutch to turn in only one direction.
