My little cousin broke the hair loom that connects the hair to her Barbie, so i designed a replacement part. The tip is very fine and can be tricky to print if you don't have proper cooling.
Looks good, unfortunately i don't have a photo of it fitted because my little cousin took it home as soon as the part was ready. I don't know about other barbies, but it should fit all those similar models, it also takes little time to print. I suggest printing it slow because the part is very small.
