I was having crosstalk on some wiring. Spent a few minutes drawing up a versatile wire twister for a variety of wiring arrangements. It works well enough :)The wires to be twisted go through the flat bottom first, as the openings are designed to angle in to bring the wires close together where they twist. It could probably use some refinement or a nice jig to eliminate the other end from twisting so after some turns the other side needs to be untangled a bit. This does make it fairly easy to somewhat control the twist and all though.
