High-Precision 3D Product Model

I'm looking for an experienced 3D designer to create a highly precise product model for small time manufacturing purposes. I have combined two products I found online as an example of what I need.

Key Requirements:
- Product modeling expertise
- High precision with all dimensions
- Ideal for manufacturing use

Ideal Skills and Experience:
- Proficiency in 3D design software (e.g., SolidWorks, AutoCAD, Rhino)
- Strong attention to detail
- Background in manufacturing processes and requirements
- Previous experience with similar projects

Please provide examples of your previous work and a brief description of your approach to ensure accuracy and precision.
