Some python scripts to decompose stl to openscad primitives
# STL to OpenSCAD Voxel Converter
A Python script that converts STL 3D models into OpenSCAD code using voxelization and greedy merging, with optional debug coloring.
## Features
- Converts STL files to OpenSCAD cube structures
- Adjustable voxel resolution
- Greedy merging algorithm reduces cube count
- Progress bars for voxelization and merging
- Debug mode with random colors for visualization
- Handles large files efficiently
## Installation
1. Clone this repository:
```
git clone https://github.com/yourusername/stl2openscad.git
cd stl2openscad
```
2. Install dependencies:
```
pip install -r requirements.txt
```
3. Usage
```
python stl2openscad.py input.stl output.scad --resolution 1.0 --debug
```
3.1 Parameters
-r, --resolution : (Voxel size in mm, default = 1.0)
--debug : Enable colored debug mode (default False)
