Have you ever tried to twist two thick wires together, but the wire kept on slipping in your fingers? No more! This is the WireTwister! It's a drill bit attachment that secures the wires with 2 2-56 screws and allows you to twist the wires together with ease!
I've included the Inventor file so you can change the screw hole to match any of your screws!
UPDATE: https://www.youmagine.com/designs/wiretwister I've moved this design to YouMagine.
When you are in your slicing software, scale the WireTwister by 10 to make sure it prints at the right size.
I printed this with 100% fill, 100 micron layer height and at 50mm/s.

To use the WireTwister put your two wires into the holes on the bottom and tighten the screws. Then put the WireTwister into your drill and start twisting!
