Manfrotto 330 Macro Bracket brand_Cinestill has a 46mm thread thatThe Manfrotto 330 is an awkward looking device that will instantly make sense if you've ever tried to set up a handheld camera with a couple of flashes for macro use: it consists of a camera platform that can be flipped from horizontal to vertical, and two adjustable arms with standard 1 4" threads on the ends (with a pair of cold shoes attached). All metal, and in excellent condition.
