Mr.C's multi-reusable zip tie (PETG) I needed a zip tie I could re-use. After not finding what I wanted, I started toying with others' existing zip tie designs, wasn't impressed, and designed this from scratch using Blender. Redesigning, testing, optimizing for least material condition, and miniaturizing, it releases by using thumb and fore-finger to pinch the center front 3-teeth upward. PETG allows sufficient strength and flex, nylon might work even better. Scale a bit larger for super zip ties, I doubt smaller scale will work. Enjoy!
