Hollow Crocodile 3D Model

I need a large (over 30 cm) hollow 3D model of a crocodile for 3D printing. I can provide a picture of the crocodile swimming that I need. It will be rigid and does not need to be extremely detailed but must generally be the shape of a real crocodile. The inside must be accessible to allow for placement of weights inside. The model can be designed to be printed in several parts that could be glued together if necessary to fit a standard printer.

Ideal skills and experience:
- Proficiency in 3D modeling software (like Blender, ZBrush, etc.)
- Experience with creating hollow models for 3D printing
- Attention to detail and ability to follow specifications
