fetus in eggshell 3d model

Create a highly detailed, single-piece 3D model of a human fetus curled in the fetal position inside a half-open egg. The fetus must be firmly attached to the inner surface of the egg, forming one solid, merged structure suitable for 3D printing. The egg shell must be smooth, undamaged, and symmetrical. The fetus should have realistic anatomy and fine details: head tucked forward, curled arms and legs, clear facial and body features. The inner surface of the egg should be organic and seamless. The entire model must be printed as one unified object with no floating or separated parts
