Robust Zipper pull replacement (Ratchet)

Might be slightly over-engineered, but I always keep a few different sizes on my key-chain. That way I'm always ready, when a zipper pull on or around me breaks. Saved me and my friends a bunch of times already.Print recommendations: 100% infill; vertical shell perimeter until the loop is fully covered for highest strength; due to very small margin between the “two parts”: avoid over extrusion; no ironing and consider lowering print speed or nozzle temp; If necessary, use pliers to “break” the two rows of teeth gently apart if over-extrusion fused them together.Installation: Remove any remains of the previous zipper pull. Simply bend the teeth apart to slide the thin outer part through the hole in the slide of your zipper. A bit of force might be necessary - depending on the slide. Once in place snap the teeth back together. Pulling on it only makes the handle hold better together.
