3D Model for Test Bench System

I need a full 3D model of a smart electrical meter test bench system.

Requirements include:
- Medium detail (no textures)
- Deliverable in STL format

Ideal skills and experience:
- Proficiency in 3D modeling software
- Strong understanding of electrical systems
- Ability to create accurate and functional designs

Please provide samples of similar work.

I would like a 3D design of a workshop-style electric meter test bench that can test different types of meters—single-phase, three-phase direct-connected, and three-phase CT-connected—all at the same time. The front of the bench should have multiple meter slots (e.g., six or more), each connected to its own Current Separating Transformer (CST) for safe and isolated testing. Above or in front of each meter, there should be an OCR camera to read the meter’s mechanical dials, and detect pulse outputs like disk movement. A central control unit or a connected laptop should be included to show real-time readings and results. The whole setup should look like a heavy-duty test bench on wheels, suitable for a workshop environment.
