Another Prusa i3 Mk2 Round Knob

The knob that comes with the Prusa i3 kit is far from the most ergonomic of knobs, so I thought I'd try some of the others and see what improvement was to be had. Thing:1734712 seems to be the most popular so I gave it a go. It was better, but I didn't like that it partially covered the cancel button, didn't think it gave enough finger traction on the circumference, and the fingertip divot wasn't really useful.

So I fixed those things.
