Complete calibration cube

ENGLISH VERSION Hello, I am here to present you the final calibration cube with specific measurement and testing capabilities. It is a 40mm x 40mm x 40mm cube designed for assessing the accuracy of a 3D printer's calibration and various printing parameters. This calibration cube serves multiple purposes: 1. Calibration on X, Y and Z Axes: It measures the printer's calibration accuracy on the X, Y and Z axes, ensuring that printed objects are dimensionally accurate in these directions. 2. Spherical Z-Circle Test: This cube assesses the printer's ability to produce correctly spherical shapes in the Z-axis, verifying that circular features are printed with precision. 3. Bridging Test: It measures the printer's bridging capabilities by including a 10mm x 10mm section with a thickness of 0.4mm, consisting of two layers from the bottom to the top. This assesses the printer's ability to create bridges effectively without sagging or deformities. 4. Support-Free Angle Testing: The cube incorpor
