PM-728VT Spindle Bushing

I printed this to make the quill and spindle a solid assembly when converting the PM-728 to CNC. Prior to this, the spindle made a noise/vibration due to the motion of the spline connection. I removed the spring and existing bushing then used a M20x1.0 nut on top of this bushing. I also loaded the space with a generous amount of "sticky grease" which is thick so it won't run out quickly.
