grabowski a0c843204d Update mechanical folder structure for multiple sub-assemblies

- Refactor mechanical/ directory to support multiple sub-assemblies instead of just enclosures
- Update mechanical/README.md with comprehensive sub-assembly organization examples
- Enhance mechanical/cad/README.md with detailed sub-assembly structure (PCB mounts, sensor housing, connector panels, cooling, etc.)
- Expand mechanical/enclosure/README.md to cover main housing, sub-enclosures, and removable panels
- Improve mechanical/stl/README.md with broader 3D printing categories including tooling, prototyping, and custom components
- Update mechanical/drawings/README.md with comprehensive technical drawing organization for all mechanical components
- Add detailed manufacturing considerations, quality control procedures, and file management guidelines
- Support complex projects with multiple mechanical sub-systems and assemblies

/mechanical/enclosure

Housing and enclosure designs for the complete system.

Purpose

This directory contains enclosure and housing designs that protect and contain the electronic and mechanical components. Enclosures may include multiple housings, covers, and panels depending on system complexity.

Enclosure Types

Organize by enclosure function and hierarchy:

enclosure/
├── main-housing/               # Primary system enclosure
│   ├── base-housing.sldprt
│   ├── top-cover.sldprt
│   ├── gaskets-seals.sldprt
│   └── housing-assembly.sldasm
├── sub-enclosures/             # Secondary or modular housings
│   ├── sensor-module-housing/
│   ├── power-supply-housing/
│   ├── interface-module-housing/
│   └── expansion-module-housing/
└── covers-panels/              # Removable access components
    ├── access-panels/
    ├── connector-panels/
    ├── display-bezels/
    └── ventilation-grilles/

Design Considerations

Environmental Protection

IP Rating: Define ingress protection requirements
Sealing: Gaskets, O-rings, and weatherproofing
Drainage: Water management and condensation control
Ventilation: Airflow and thermal management

Mechanical Requirements

Structural Integrity: Load bearing and impact resistance
Mounting: Wall mount, panel mount, or free-standing
Access: Service panels and component accessibility
Cable Management: Entry points and strain relief

Manufacturing Considerations

Material Selection: Plastic, metal, composite materials
Manufacturing Process: Injection molding, machining, sheet metal
Tolerances: Fit and finish requirements
Surface Treatment: Painting, anodizing, texturing

Electrical Integration

EMI/RFI Shielding: Electromagnetic compatibility
Grounding: Electrical safety and noise reduction
Cable Entry: Glands, connectors, and feedthroughs
Heat Dissipation: Thermal interface to internal components

File Organization

Main Housing Files

Base/Bottom: Primary structural component
Cover/Top: Removable or hinged access
Sides/Walls: Structural walls and mounting surfaces
Internal Structure: Mounting posts, ribs, and supports

Sub-Enclosure Files

Modular Housings: Self-contained sub-assemblies
Protective Covers: Component-specific protection
Interface Panels: User interaction surfaces
Mounting Brackets: Attachment to main housing

Hardware and Fasteners

Screws and Bolts: Fastening hardware specifications
Hinges and Latches: Access mechanism components
Gaskets and Seals: Environmental protection components
Inserts and Threads: Threaded fastening points

Material Specifications

Document material requirements for each component:

Mechanical Properties: Strength, flexibility, durability
Environmental Resistance: UV, chemical, temperature
Electrical Properties: Conductivity, dielectric strength
Regulatory Compliance: UL, CE, RoHS requirements

Assembly Instructions

Assembly Sequence: Order of component installation
Torque Specifications: Fastener tightening requirements
Sealing Procedures: Gasket installation and verification
Quality Checks: Dimensional and functional verification

Testing and Validation

Environmental Testing: Temperature, humidity, vibration
Ingress Protection: Water and dust resistance verification
EMC Testing: Electromagnetic compatibility validation
Mechanical Testing: Drop, impact, and load testing
