Calibration Check Dice

Dice-Style Test Cube This precision test cube is designed in the shape of a standard die, measuring 25 mm x 25 mm x 25 mm. Each of its six faces is marked with pips (dots) corresponding to the number on a dice side, but with a functional twist: Hole Diameter: The number of pips on each face indicates the diameter of the holes on that side. For example, the side with four pips has four holes of equal size, with diameters set to “4mm.” Hole Depth: Beginning with the side marked “3,” the hole depth increases progressively by 1 mm per side, ranging from 1 mm (side 3) up to 6 mm (side 6). Chamfer: All external edges of the cube include a 1 mm chamfer at 45°.. This makes the cube both a functional gauge, ideal for demonstrating hole sizing and depth progression in a compact, dice-inspired format.
