Mechanical design files for all physical components and sub-assemblies.
|
|
|
|
## Purpose
|
|
This directory contains mechanical design files for the complete physical system, including multiple sub-assemblies, enclosures, mounting hardware, and mechanical interfaces.
|
|
|
|
## Directory Structure
|
|
- `cad/` - Editable CAD models and assemblies
|
|
- `drawings/` - 2D technical drawings and specifications
|
|
- `enclosure/` - Housing and case designs
|
|
- `stl/` - 3D printable files for all components
|
|
|
|
## Sub-Assembly Organization
|
|
For projects with multiple mechanical sub-assemblies, organize by function:
|
|
|
|
```

## File Types
|
|
- **CAD Files**: Native CAD formats (.sldprt, .step, .iges, .f3d)
|
|
- **Drawings**: PDF technical drawings and DXF files
|
|
- **3D Models**: STL files for 3D printing, STEP for manufacturing
|
|
- **Assembly Files**: Complete system assemblies and sub-assemblies
|
|
|
|
## Design Considerations
|
|
- **Modularity**: Design for easy assembly and maintenance
|
|
- **Manufacturing**: Consider fabrication methods and tolerances
|
|
- **Materials**: Document material specifications and requirements
|
|
- **Interfaces**: Define mechanical interfaces between sub-assemblies
|
|
- **Thermal**: Account for heat dissipation and airflow
|
|
- **Accessibility**: Ensure access for assembly, service, and repair
|
|
|
|
## CAD File Management
|
|
- Use consistent naming conventions across all files
|
|
- Maintain assembly hierarchy and relationships
|
|
- Include material properties and finish specifications
|
|
- Document design intent and critical dimensions
|
|
- Version control CAD files with descriptive commit messages
|
|
|
|
## Manufacturing Integration
|
|
- Coordinate with PCB dimensions and mounting holes
|
|
- Consider assembly sequence and tooling requirements
|
|
- Define tolerances and critical dimensions
|
|
- Specify surface finishes and treatments
|
|
- Include inspection and quality requirements
|
|
|
|
## Documentation Requirements
|
|
- Assembly instructions and procedures
|
|
- Bill of materials for mechanical components
|
|
- Interface specifications and mating requirements
|
|
- Manufacturing and fabrication notes
|
|
- Testing and validation procedures
|
