18650 Flexing battery holders with integrated spring and tp4056 slot

I needed the flexing battery holder to hold my tp4056 charging circuit. I've been using it for years. It was one of my first customization projects. It took forever using sketchup. fortunately now I know how to use openscad so more is coming on this in the future.
