Creality CR-10 Ball bearings filament roll support

thingiverse

This is a filament spool support designed to complement the stock one on the CR-10. It incorporates ball bearings and features two lateral guides for enhanced stability. This upgrade is not essential, but it can be considered if you've experienced issues with print failures due to spool problems in the past. The primary objective of this design is to minimize the risk of print failure by reducing the likelihood of filament-related mishaps. The filament spool smoothly rolls on ball bearings, minimizing the force required from the extruder and ensuring a seamless movement. Two lateral guides prevent the filament spool from shifting or tangling on the axis. This system is specifically designed for use with spools that have a hole diameter of 52mm or greater. The bearings used have an internal diameter of 5mm, an external diameter of 16mm, and a thickness of 5mm (type 625). Four such bearings are required for the complete setup. To assemble the system, you'll need to print four "Bearing support" models and two "Lateral guide" models. First, attach one bearing to each bearing support and then clip the assemblies onto the original spool holder axis. Repeat this process twice to create two supports that can be slid along the axis for adjustment. The lateral guides are installed as shown in the accompanying picture. If your axis has a diameter of 30.3mm, the guides will fit snugly, which is intentional. To facilitate smooth movement while maintaining sufficient friction, sand the interior of the hole to create a slight clearance. Secure everything with the stock nut, taking care not to block the rotation of the spool with the lateral guides.
