Prusa ML3S+ Ball Bearing Spool Holder

Compact and easy to print spool roller/holder for the Prusa MK3S. Uses 4 608 skateboard bearings to provide a smooth rolling with consistent tension on the filament unlike the standard center bar holder which sticks & slides.

Quick and easy filament roll changes. Can handle all roll sizes. Sits compactly on top of the printer frame.

Prints in place without supports. PETG recommended.
