The prompt
Generate a parametric 3D CAD model of a rear airflow plenum insert for a climate control cabinet. The overall bounding box dimensions of the main plenum body should be 15.7 inches wide, 1.25 inches deep, and 28.0 inches tall. The back face should be a solid flat wall. The front face should be open but feature vertical airflow separator vanes spaced 2 inches apart running the full height of the part. Most importantly, extending forward from the left and right outer side walls of the plenum, generate 7 horizontal shelf-support ledges on each side. Each ledge should protrude forward by 0.5 inches, have a vertical thickness of 0.375 inches, and be spaced evenly at a 3.875-inch vertical pitch, starting 2 inches from the bottom. Expose the total height, overall width, and the vertical rack pitch spacing as editable parameters so I can adjust the shelf spacing later.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
