The trigger for the dog poop scoop I use broke, so I made a replacement. The replacement has 4 pieces. a left and right handle and a left and right trigger. The trigger pieces get glued together with the end of the cable inside. The handle gets bolted together. One of the bolts also serves as the pivot point for the trigger. I printed in PETG with no supports. This handle is specifically designed for the Diamond Visions Super Pooper Scooper. The last picture is one of the original handle that had broken.
