Bobbin Lace bobbins - several sizes
thingiverse
Bobbin Lace bobbins in several sizes and styles, printed flat in two parts and epoxied together. PLA, PrusaMK3S+ Large at 20% infill should give you enough weight for thick threads, add a couple balls of bb shot to the chamber (with epoxy so they don't rattle) for more weight as desired but I found that they are good at 20% without weight for #10 crochet thread. Ball End and the remaining small ones with 1 bb in the chamber, glued with CA or CA gel weigh ~3 grams and are approx 4"-4.5" long.
