thingiverse

This is a precision-engineered ball bearing filament spool core designed specifically for the innovative SPANNERHANDS Spool System MK6. The addition of high-quality ball bearings eliminates binding and ensures ultra-smooth rolling of the spool. The core diameter has been expertly reduced from 52mm to 48mm, making it compatible with a wide range of filament spools. The roller core features two bearings with precise measurements: 32mm outer diameter 13mm inner diameter 10mm width An alternative version is available for bearings with an inner diameter of 12mm. To ensure a secure fit, the bearings may be slightly loose due to printer tolerances. This issue can be easily addressed by applying a few strips of electrical tape to snugly fit the bearings within the core. The mounting holes on the screw cap are spaced at 51mm (2 inches), allowing for effortless attachment of custom handles.
