If you're building a printer or other machine that has long cable runs, twisting the wires helps keep everything neat. I designed and printed a wire twister a few years ago and used it for many projects but never liked having to use a screwdriver to clamp the wires in the tool. I recently designed a new tool to use wago lever nuts to clamp the wires and it is a huge improvement.
All you do is put the spinning clamp in your electric drill/screwdriver, clamp the wires into the Wagos, and spin.
