I truly like the PTFE simple connector by Jorn-H on https://www.thingiverse.com/thing:3093690 for quick manual color changes. However, I keep losing the clips, so I redesigned from scratch adding a keyed face and friction clips. The remix is a bit more compact, and you can't lose the clips although you might break them off if heavy handed. I have not broken one yet, fingers crossed.
