Working on the next pic for that au from my most recent posts. I’ve been calling it “mini cap” in my head but I need a good name for it. Any ideas?

Alternatively, does anyone know what any existing names for this au might be? I know i’m definitely not the first to draw or write around this concept. I remember hearing “original recipe” once, and I know of “shrinkyclinks,” but that isn’t quite the same idea.
