Maxnomic gamer chair fix

My one year old maxnomic gamer chair was a bit vobby, and made a click sound every time you move around in it.

The reason was that the steel shaft in the buttom of the chair, is a 6mm shaft, and the hole its fixed though is a 12mm hole. Thats crappy.

I made this fix for it. Maybe you have the same problem and need a quick fix.
