Fazua Ride 50 socket for bottom bracket

I had cracking sounds on my Fazua Ride 50 bottom bracket and i figured it out to by a lose lid of a bearing sit, so i designed something to fix the problem.
(i already checked the mounting screws)

this is my design for a special socket to tighten the lid of my fazua Ride 50 bottom bracket.

1. take off the pedal arm on the left side
2. take off the thin locking ring on the axel
3.put the socket in place
4.screw the Bolt for the pedal arm back on (hand tight) so the socket do not slip out of the teeth
5.tighten down the lid.

the socket is moste likely a one use tool only, but it should do the job.
