Hex Key adapter for drill by SamuelRilling

Last crawled date: 3 years, 5 months ago

A very useful little contraption i devised when i wanted to use a drill to tighten several bolts at the bottom of a build at an angle, so the regular drill hex key didn't cut it. The bottom of some regular handheld hex keys have a "rounded" bottom for that purpose, so instead of cutting the tool i designed this workaround so i can just snap it on around the key and drill away.
I designed it for a tight fit around a 3mm key, so for other size of keys just scale it by an according fraction. Just snap it on and fasten it with zip-ties. Works like a charm!
You should also consider further scaling it just a little if your prints tend to not be accurate enough, specially for small keys. Also, some movement between the pice and the key might be desirable (the drill won't wobble as much).
It is intended to be printed on it's back (the small back surface), But i made an untested, unsupported version if you care more for ease of printing.
