Ring1 and ring 2 make one type of divider - solid, 4.5mm thick fits a 200mm diameter spool with a 110mm diameter core. One time use i.e. fit to spool and getting it off will break it. Some changes to make it more user friendly and quicker to print needed

Photographs show one of each type of spool divider.
Work in progress because a quick, simple design needs to be done for this and should include a method to label the filament, clip the filament when not i
