Geeetech A30 Leveling wheel

I tried making the wheel for the CR10 but the hole was to big.
There is one on here that said it fits an A30 but as I was playing with Fusion 360 decided to design one of my own.
This one fits on the A30 hand nut from the top and so can not fall off, although it is very tight and needs knocking on, to make it easier to fit you may want to scale it up 1 or 2 percent
