A replacement for the macro flash mounting ring for Godox MF12 flashes, that can be attached to the front of an Olympus 90mm macro using the lens hood bayonet mounting rather than the filter rings (and is thus easy to attach/remove). There's also a gap in the ring rather than the spring-mounted section in the original, which I find makes it much easier to take the flashes on and off.

Includes a ring at the front for mounting a diffuser such as the one described at https://www.instructables.com/Godox-MF-12-Flash-Diffuser/

Use a piece of 1mm wire and a 2mm diameter 4mm long spring to attach the clip.
