V1 Calibration Helix for Delta type printers comprises three cubes measuring 5x5x10mm each, featuring a hole in the center. The cubes are carefully arranged at precisely 120-degree intervals to ensure optimal precision. We would appreciate confirmation regarding the dimensions of these pieces and whether the printing bed is concave or convex. Notably, the axes are clearly labeled with their corresponding letters, situated at a distance of exactly 50mm from the center. V2 Calibration Helix for Delta type printers consists of three cubes measuring 5x5x10mm each, centered around a cylindrical shape. The cubes are strategically arranged at intervals of 120 degrees to guarantee accuracy. We would appreciate verification regarding the dimensions of these pieces and whether the printing bed is concave or convex in nature. Furthermore, the axes are identified with their corresponding letters and are positioned at distinct distances: 43mm from the Z-axis, and 42.0965mm from both the Y- and Z-axes.
