M3D Crane Quad 4mm Bed Adjustment Knob

I don't know why, but my locknut knobs where a smaller size from M3D than MasterRC's design, so I reduced the size to fit a standard M4 LockNut. Works great, thanks masterRC!

Also, Don't forget to print out masterRC's limit switch for this mod! https://www.thingiverse.com/thing:3925942
