Bit-Brace Hex Kit

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5182454.

Convert your traditional Bit Brace hand drill from the classic square attachment style into the modern hex / quick release system, all without needing an extra conversion piece around. This part was modeled from the dimensions of an original set of chuck teeth and redesigned to account for the strength limitations of PLA.

It can accept a wire spring like a normal vice clamp, but works great without it too! If you need to adjust any dimensions for your own tool, the original blender project file is included.

Prints great without supports! I recommend printing at 70% infill or higher to prevent any collapsing under high pressure.
