Logitech Z3 Cable Holder

My Logitech Z3 is an old speaker (15+ years) - that still does a decent job. It has one big flaw and that's the plug that connects the satellite and the remote to the base. Just touching the cables creates noise because of the unstable plug.
I would have loved to just replace the damn thing with something better for the job. Unfortunately the inner setup of the base is also done horribly. There is no easy way to change the plug. So I resorted to a mechanical workaround that fixes the plug in place. Works flawless for me.

Needs a long enough M3. I think it was 40mm - but not sure anymore.
