3D Model: Create A Highly Realistic, Anatomically Accurate 3D Model Of A Horse, Optimized For STL Output. The Model Must Include Fine Details Such As Muscles, Veins, Fur Texture, Mane, Tail, Ears, Eyes, And Hooves With High Resolution And Dense Mesh Suitable For 3D Printing. Prioritize Maximum Surface Precision, Clean Topology, And No Structural Defects. Ensure The Model Is Watertight And Ready For Direct 3D Printing In STL Format. Avoid Stylization; Aim For Lifelike Proportions And Realistic Anatomy Based On A Thoroughbred Horse. Full-body Model Required. Output Format: STL Target Use: High-resolution 3D Printing Additional Conditions: High Polygon Count, Detailed Surface Texture, Physically Correct Volume, Printable Without Supports If Possible.
