Smaller Bed Level knob

This is a slightly smaller version of the original cover for the bed leveling screw.

The problem I had with the original was, that when used on the left side of the bed, the fit was too tight, and the knob head was touching the axis motor, causing it to rotate as the bed was moving back and forth.

So I made the radius of the knob about 1mm smaller (while keeping the inside space at the same size) which removed the problem.
