spool holder bar adapter for smooth rotation

Summary hey guys! this its an spool holder i designed to attach on holding bars, helping the spool to move smothly when extruder push the filament with minimal friction. the bar i used its an auminum one with 16mm diameter, bearings for the holder are conmon ABEC, and on sides i put 2 pieces of steel bars of 6mm diameter so reduce friction against plastic. easy to print and also makes longerthe life of the extruder, since no need to push harder to move filament. videos finished:https://youtu.be/0PAfJaPZ1bA https://youtu.be/HpQHCuLzQLA Print Settings Printer: Malyan m200 Rafts: No Supports: Yes Resolution: 0.2 Infill: 20%
