line throw weight shells

This is a mold for a 1 oz lead sinkers designed specifically for use with a fishing rod to propel across tree limbs, facilitating retrieval of a cord that pulls up a wire antenna. I typically print two duplicate copies in different colors before combining them during assembly to enhance visibility. I created this design to enable easy passage through twigs and leaves while remaining easily visible and minimizing the likelihood of wrap-around on branches during retrieval. There are two distinct versions available: one for ball-shaped sinkers and another for football-shaped "bullet" sinkers. Each individual half is clearly marked with a number (1 & 2) to facilitate assembly when combining different colored parts. A complete mold consists of both numbered parts combined. To minimize the risk of shell damage from impact, it's recommended to print in TPU material. Using 99% infill in TPU will also add some weight to the mold.
