The prompt
Generate a 3D solid model of a mechanical locking block assembly aligned to origin (0,0,0) at the center of the main bore axis and front shoulder face. The main outer envelope is a solid block 88mm long (X from +10 to -78), 40mm wide (Z from -20 to +20), and 40mm high (Y from -15 to +25). Subtracted along the X-axis is a 6.7mm coaxial through-bore, a 25.27mm threaded socket (1.000"x16 TPI) extending from X=0 to X=-17.02mm, and a 45-degree extractor chamfer cut at X=-2mm in the +Z/+Y quadrant. Milled through the top and rear is a 28mm wide open channel (Z from -14 to +14) extending from X=-17mm to X=-78mm, with 4mm wide by 2mm deep guide tracks recessed along the inner side walls. Intersecting the channel at X=-61.47mm and Y=-5mm is a 6.35mm transverse pin hole along the Z-axis, paired with an 11.5-degree forward-tilted angled flat seat. Two 8mm conical feed ramps tapered at 32 degrees are cut into the bottom breech face at X=-17.02mm and Y=-3mm, offset at Z=-4mm and Z=+4mm. A parallel 11mm clearance bore runs along the top at Y=+25mm, Z=0. Extending underneath is a 20mm (X) by 16mm (Z) by 15mm (Y) lower hinge boss featuring a 6.35mm transverse hole centered at X=-10.41mm, Y=-22.99mm.
