coiled snake 3d model

High-detail 3D model for 3D printing: A realistic snake coiled in a vertical spiral. The snake must have a hollow cylindrical space through its center (76mm diameter) as if it is tightly hugging a pole. Crucial: the inner side of the snake's body must be concave/coved to fit perfectly against a 3-inch tube. The head of the snake is resting flat on the very top of the spiral, looking forward. Highly detailed reptilian scales texture. Clean manifold mesh, watertight, single object, no base
