There is a string with plastic beads for moving the blinds up and down. However this string has two ends and the original part that kept the two ends together broke. I 3d modeled a screw, cut it in half, and embedded a negative of the bead string in there. Further I modeled a nut for the screw. With that I could capture the two ends within the screw and the nut holds everything together.
