external trigger mount for Jinbei studio flash (designed for DPIII)

This is my somewhat overengineered approach to mount a hotshoe-based wireless trigger on a Jinbei studio flash (DPIII 300W).
The mount fits thigtly into the slot on top or underneath the flash' housing and is secured by a M4x8 hexagon socket screw and a 2020 slot nut that has to be machined/filed at the bottom to decrease its height.

Please let me know wether the mount fits to other Jinbei studio flashes as well.
