Ergonomic 1/4" Hex Bit Screwdriver Handle (3D Printable)

A reverse-engineered, highly ergonomic screwdriver handle optimized for functional 3D printing. This model features a standard 1/4" (6.35mm) hex socket designed to accept real metal driving bits. Print this to replace broken handles, build your own custom toolset, or practice high-infill functional printing. It is designed to be an actual usable tool, not a fragile plastic toy.
