About this 3D model

Simple impact driver bit holders. Tired of the annoying one they all come with that just rnd up losing the actualy holder and they just turn into a pile of bits in a broken plastic box. Reccomend pinting in a flexable filament with at least 3 shells (4 best) might be a tad tight for hard plastics. https://youtu.be/FMcLOF-PqWU
