A highly detailed, realistic 3D model of Santa Claus’s sleigh. Crafted from polished, rich red wood with gold trim, ornate carved patterns, and metal runners with a slightly weathered steel finish. The sleigh should have plush, deep-red velvet seating, soft highlights, and realistic stitching. Include subtle seasonal elements such as small bells, leather straps, and decorative holly. Proportions should be functional and believable, designed to carry gifts. Soft winter lighting, accurate materials, and a physically plausible structure. No Santa or reindeer — sleigh only.
