This model is a stringer used to bend a bow. Is is designed to be printed in TPU and hold tightly the branches of your bow without risks of damage. This design is inspired from the leather stringers you can find on the market. To make it just print one of each of the files (top and bottom in TPU, Bead in PLA or ABS) and assemble according to the pictures. You will need about 2M of cord, the cord diameter should be between 2 and 3 mm. Depending on your printer's characteristics you may want to use supports inside the bow sockets as TPU does not provide the best overhangs.
