Could use some opinions! I was hunting for a decent, useable screwdriver for my keychain, and came up with nothing. So I designed and 3D printed this:
It uses standard sized bits available at any hardware store so I can customize it to what I expect to need. I'm working on a clever keychain quick-disconnect.
If it interests others I can explore the possibility of machining this out of aluminum and/or titanium. Please let me know what you think!!
