# CQ-Enclosure

A parametric IP66-rated enclosure generator for 3D printing, built with CadQuery. This package allows you to easily create customized enclosures with gaskets and various screw mounting options.

All components (box, lid, and gasket) can be exported as STEP files for compatibility with any CAD software and 3D printing workflow.

## Features

- Fully parametric enclosure generation
- IP66-rated design with gasket
- Multiple screw mounting options:
  - Inside or outside box mounting
  - Wood screw or machine screw support with countersunk head
  - Configurable corner and middle screw positions
- Mounting holders for attaching the enclosure
- Automatic generation of:
  - Main enclosure box
  - Matching lid
  - Gasket for water-tight seal

## Installation

Requires python 3.10 or higher.

```bash
pip install cq-enclosure
```

## Usage

See the [examples](examples/) directory for complete usage examples.

## Examples

```python
box, lid, gasket = Enclosure(
    box_inner_width=31.0,
    box_inner_length=71.0,
    box_inner_height=31.0,
    screw_location=ScrewLocation.INSIDE_BOX,
    middle_length_screws=True,
).build()
```
