Well originally it was just the shaft that just broke
off.. 
I tried supergluing a piece of allen wrench in there,
but then it froze the insides of the dial by the

What a bonehead move!
A few choice words did not fix it.
Im currently looking up what a potentiometer is.
So far it looks like the dial that im referring to.
In fact it looks like this:

Yes, only one axis and I manually correct the other.
