Standalone Spool Holder

This is a 3d printed spool holder with no bearings required. With the print time being rather short. materials required for assembly are minimal. There are some problems with friction on the rollers and the holder on surfaces. It can be countered by putting rubber feet on the holder and wrapping a rubber band around the baring to ensure the spool spins smoothly. Recommendations for improvements would be appreciated.
