I created this organizer for a Sherline Thread Cutting tool. It includes slots for all change gears and other associated attachments. Note the text near the gears needs to be printed in a .2mm nozzle as the font is small; otherwise you can use a label machine as I did. The gear labels are: “40|38|36|34|32|30|28|26|24|22|20|20” and “50|100|100|127”
