The prompt
Create a 3D CAD model of a straight hollow square tube with a cross hole near each end. Units: millimetres. Geometry: - Tube: 114 mm long with a 6 mm x 6 mm square outer cross-section, symmetric about its mid-length. - Bore: a 4 mm x 4 mm square hole running the full 114 mm length, centred on the cross-section, open at both ends. This leaves a uniform 1 mm wall on all four sides. - Cross holes: one circular through-hole near each end, radius 1.7 mm (diameter 3.4 mm). Each hole axis is perpendicular to the tube's long axis and passes through both opposite side walls, in the same direction for both holes. Each hole is centred on the tube's centreline, with its centre 3 mm from the end face. The top and bottom walls stay intact. - Hole spacing: exactly 108 mm between the two hole centres, measured along the tube's long axis. - All edges sharp, no fillets or chamfers. Single solid body.
