Spool hub with bearings

thingiverse

Manufacturers provide a spool hub that includes bearings, specifically designed to accommodate spools featuring hole diameters measuring between 50mm and 60mm in size. The hub itself is engineered to support bearings with an outer diameter of precisely 28mm and inner diameter of exactly 12mm. This particular spool hub is highly recommended for enhancing the performance of flexible filaments during the printing process by significantly reducing friction within the spool.
