A calibration cube that's simple in design. It needs to measure precisely 20 millimeters by 20 millimeters by 20 millimeters in size. This cube must have a square hole on one side, measuring exactly 10 millimeters by 10 millimeters by 5 millimeters. Additionally, there should be a round hole with a diameter of 10 millimeters. The cube also requires another type of hole - a square hole that includes a ball. This square hole needs to measure 10 millimeters by 10 millimeters by 5 millimeters, and the ball must have a diameter of 8 millimeters. On top of this cube, there should be four small holes, each measuring 4 millimeters by 4 millimeters. Lastly, two pillars are needed - they need to be 1 millimeter in width, 3 millimeters in depth, and 10 millimeters in height.
