Modular Thread & Yarn Spool Holder

UPDATE 3/28/25 - Added print profile for a version of the struts that has removable/replaceable pegs. Tight tolerances, but allows you to replace broken pegs and remove them for easier transport/storage! This 3D-printable modular thread spool holder is designed for durability, easy printing, and expandability. Organize your thread spools and bobbins on this simple desktop holder. Looking for a similar shelf to hold other small sewing bits or anything similar, check out my ModuTier - Modular Display Shelf, which can also hold spools on the recessed shelf version in a different way! The shelves from this model should fit in those side pieces if you want a perfectly vertical spool holder! Unlike previous designs where pegs could snap under stress, this version is optimized for strength while maintaining a fast, support-minimized print on standard Bambu Lab plates. A second print profile for a “middle” piece is designed to allow you to combine two sets of struts to expand the storage in on
