A tool for twisting electrical wires
I'm wiring a new printer and needed to make a lot of twisted pair wires to connect everything to the controller ...board and power supply, so I designed this tool.
Materials and methods
This is a good use for the random short pieces of filament you have left at the end of a spool because it doesn't take much filament. You can use PLA or ABS. I printed in 0.25 mm layers.
You will need 8x 6-32 x 1/2" long screws.
Just clamp the wires (any size up to about 5 mm diameter) in the two pieces, chuck one in your drill and clamp the other in a vise or clamp it to a table top, pull the wires tight and run the drill slowly, keeping tension on the wires as they twist.
