Upgrade the old Spool with attached parts

If you are using old spools, then you can add a few parts for improving the performance. Side guide may help to maintain the material without twisted. And if the material widing is winded with worst condition, then you can add spool disc guide. It will prevents the material out from its core. Also, you can use previous bearing roller but if you use latest one. that will be better for guiding spool.
