Redesign triangle and parts for solar mounting system based on actual drawings

I am looking for a skilled freelancer to help me redesign all parts of a solar mounting system based on actual drawings.

For the solar mounting system such as per uploaded document, I have the basic technical drawings from each 5 pcs individual part triangle + back-plate + side plate + L profile + ballast plate as a .stp file.

I need:

• Redesign the triangle + back-plate + side plate + L profile + ballast plate - slightly (changes such as radius, profiling).
• Create an assembled drawing with poprivet + tubtarra insert etc..
• Make the drawing from pp footing plastic part based on sketches and the holes foreseen in the triangle.

Deliver all this in .stp file.

If there is a possibility to create line-drawings and renderings, then all separate parts, half assembly and a complete assembly for 10 panels can be made, for our catalogues.






Specific requirements:
- Redesigning all parts of the system, including the triangle and other components
- Implementing specific changes and improvements that I have in mind
- Delivering the redesigned drawings in STEP file format

Ideal skills and experience:
- Proficiency in CAD software
- Experience in solar mounting system design
- Strong attention to detail and ability to interpret and implement design changes accurately
