Toldi sewing thread holder

Model for adapting Toldi sewing thread spool to a sewing machine that has a thread holder with a holder pin being smaller than 4,5 mm in diameter. Had a problem with my thread spool wobbling around my old singer 15-90 and decided to model a spool holder that keeps the thread in place and has a widened bottom so the thread wont get stuck. Hope you enjoy! Printed using Sunlu PETG with a 0.6mm
