Drill Chuck Key - 1/4" Pilot

thingiverse

Here's a drill chuck key for a 1/2" capacity chuck with 1/4" pilot hole, and it even works! It meshes quite nicely with the teeth on the chuck. Modeled with measurements from an existing K32 type key. Plastic probably isn't the best material for this kind of thing, so I'll eventually use this to cast it in metal if I want it to be functional. This will probably serve as a backup if I lose or break the real thing. Still, print in PETG or ABS with high infill.
