The prompt
Generate a parametric 3D model of a heavy-duty T-handle hand digger for a foundry casting pattern. The handle is a standard solid cylinder T-bar. The main spade is flat, rectangular, and ends in a sharp triangular spade tip. Crucial: The neck connecting the handle shaft to the spade blade must be heavily reinforced, thick, and blended with a large radius fillet to prevent brittle cracking in cast metal. Add a 3-degree draft angle taper to all vertical edges for clean sand-mold extraction. Include blocky, beveled serrated teeth along both vertical edges of the spade blade.
