Anycubic Kossel helix calibration (X,Y & Z)

V1 Calibration Helix for Delta type printers consists of three cubes (5x5x10) mm and a hole in the center. Arranged the cubes to 120 degrees each. Lets know if the size of the pieces is correct as well as the concavity or convexity of the printing bed. The axes are identified with their letters and are at a distance of 50 mm radius
