Generate a 3D CAD model of a Little Free Library enclosure in inches: Base Plate: 21" wide by 20" deep rectangular base with a centered 3.5" x 3.5" square cutout. Set wall inset margins 1" from the 21" edges and 1.5" from the 20" edges. Enclosure & Roof: Vertical walls rising 36" to the eaves, topped by a pitched gable roof peaking at 48.5" total height. Interior Shelving: Two horizontal shelves at 14" and 25" from the base Post & Support Braces: A 22" tall, 3.5" x 3.5" square vertical post centered beneath the base, supported by 4 angled braces (one on each face) each measuring 12" in diagonal length with an 8.5" horizontal projection.
