The prompt
A highly rigid mechanical cross saddle for a CNC machine, dimensions 600mm length, 600mm width, and 120mm height. The top surface has two flat parallel mounting steps running the entire length, spaced 350mm apart, with M12 tapped holes every 60mm to mount size 45 linear guide rails. The bottom surface features 4 rectangular mounting pads for size 45 flanged linear blocks. In the exact center of the saddle, create a 60mm diameter through-hole for a ball screw shaft, surrounded by a flat circular mounting face and a bolt circle of 6 M8 tapped holes to mount a ball screw flange nut. Shell the bottom to create internal cross-ribbing (webbing) with 15mm wall thickness for high structural rigidity
