1. Rectangular Calibration Block With Four Holes
Prompt
Create a single solid STEP model in millimeters. The part is a rectangular block, 100 mm long in X, 60 mm wide in Y, and 20 mm tall in Z. Center the block on the XY origin, with the bottom face at Z = 0.
Add four vertical through-holes, each 8 mm in diameter, located at X = +/-35 mm and Y = +/-20 mm.
Add a 2 mm chamfer to the top perimeter edges only. Do not chamfer the holes.
Export as a STEP file.
