Calibration Beams for horizontal alignment of x axis

Two beams for lowering and leveling the x axis of the CR-10 S5 printer before starting the print. 

Since stepper motor and extruder are located on the left side of the x axis, the axis lowers down by itself when stepper motors are not engaged. Before starting the print, place the two beams on the frame of the printer and lower the x axis until both sides sit on the beams. Lift the x axis and remove the beams.
