The prompt
Create a 3D CAD model of a necked compression member: a hollow square tube end at each end, joined by a thin flat web. Units: millimetres. X runs along the length from 0 to 56. The cross-section is centred on the X axis (y = 0, z = 0). Symmetric about mid-length (x = 28). Geometry: - End stubs: two square-section stubs, 6 mm x 6 mm outer (y = -3 to +3, z = -3 to +3), 8 mm long each: one from x = 0 to 8, the other from x = 48 to 56. - Bore: each stub has a 4 mm x 4 mm square bore (y = -2 to +2, z = -2 to +2), open at its outer end face and 5.5 mm deep, leaving 1 mm walls on all four sides and a solid 2.5 mm block at the inner end of the stub. - Cross holes: one circular through-hole of radius 1.7 mm (diameter 3.4 mm) in each stub, axis along Z, passing through both side walls (z = -3 and z = +3), centred at y = 0. Hole centres at x = 3 and x = 53, so exactly 50 mm between the hole centres. - Neck: a flat rectangular web joining the two stubs, from x = 8 to x = 48 (40 mm long), 1.14 mm thick in Y (y = -0.57 to +0.57) and the full 6 mm in Z (z = -3 to +3), so its faces are flush with the stubs' top and bottom faces. - Single solid body. All edges sharp.
