Over-engineered JST connector pliers

On Printables there are many variations of pliers designed to pull [JST connector](https://en.wikipedia.org/wiki/JST_connector) plugs out of their sockets. To me, they were all sub-optimal. I decided to design some JST connector pliers that addresses all the deficiencies I found. The original plug-pulling pliers and derivatives probably came from [Micro Center](https://www.printables.com/model/367156-jst-connector-pliers). My design is original, done from scratch in OpenSCAD, and customizable. It's even possible to make other kinds of pliers from this. Improvements in this design over others available: * Jaws are shorter to provide greater leverage with lesser handle force. * Jaw teeth are parallel when pliers are open to the width of a JST plug. * Parts snap together, and stay together, with no extra fasteners or tools. * Large contact area between handles and hub (3X other designs) provide maximum strength at a high stress point. * Leaf springs open the pliers automatically. * Handle cross section is rounded on the outside for comfortable grip, without grasping flat beveled surfaces. * Handles are tapered where forces are lesser, to save material. * Handles are longer, enough to fit adult hands. * Handles are closer together for easier handling. * Optional finger bumps make it easier to pull JST plugs without the handle slipping from your grasp. * Optional eyelet is included for hanging the tool on a hook or peg board. The overall design can be customized in many ways using the OpenSCAD customizer. Update 10 May 2023: Made clip thinner to prevent breaking when printed with PLA, which is too brittle for the original thicker clip. Split into separate STL files for Cura users.
