If your spinner uses a .25" shaft (Fultra & TwistyGrip both do), look at the link below.
The knob is the worst part about both of these spinners b/c it looks like a volume knob. But it was all we could find that wasn't $15.00.
There is another knob that I found - it is about $4-5 dollars - but cheaper in quantity. If we get a group that wants some of these I could place a bulk order and then sell them.
