Hey Guys

I tried to drill through it and put a grub screw in. The grub didn't really bit, but it did push in some plastic and make it a tighter fit and it is now working again. (for now). I may try to think of a more permanent solution.

I know it's only $13, but hell, it only took a few minutes and it's up and going. If it breaks again I'll maybe have a new solution in my head already
