3D Design for Fish Feed Extruder

I need a detailed 3D model of a Screw and Barrel Fish Feed Extruder Machine. The model should be created in AutoCAD and include:

- Material specifications
- Exact dimensions
The machine is intended to feed fish, I can provide specs).

I can provide sketches or a rough idea of how it should look/work.

I need a design that can actually be built, not just visualized.

Ideal skills and experience:
- Proficiency in AutoCAD
- Experience in designing industrial machinery
- Attention to detail for accurate specifications
