Grabber I3 Bed Auto Level planar bed support - Y axis

Bed Auto Leveling software compensates only planar (1 plane = 3 points, not 4) distortions on the heated bed. If you fix the bed at 4 points using screws you are doomed to have a paraboloid. That is: Your table is warped and no linear BAL software will fix it.

This parts fixes this. They are designed to be attached to the Y axis car and provide a support that allows the bed to be layed as plane.
