fetal egg sculpture 3d model

Create a detailed, high-quality 3D model of a human fetus curled in the fetal position inside a half-opened egg-like shell. The shell must be smooth, unbroken and symmetrical. The fetus should be realistically shaped, with clear anatomy, curled knees, small arms and head tucked forward. The interior of the shell should be smooth and organic, without cracks. Preserve the overall composition: a fetus lying inside a half egg. The final model must be solid, clean, high-resolution and suitable for 3D printing.
