I wrote this code as an exercise in procedurally generating 3D-printable objects.

The algorithm creates six pieces that fit together to form a cube. Since the puzzle is randomly generated, even the puzzle’s creator can have the satisfaction of solving it for themselves!

For a full description of the algorithm, see the blog post.

Requirements

First install SolidPython and Numpy:

``` pip install solidpython numpy ```

Usage

To run the script:

``` python puzzle_cube.py [--size SIZE] [--shape X Y Z] [--stl] ```

Optional arguments:

• size — The size-length of a single cell in the puzzle. Default: 10 mm.
• shape — The dimensions of the puzzle. Default: (4, 4, 4)
• stl — Attempt to generate STL rather than SCAD files. (Requires OpenSCAD)

For example:

``` python puzzle_cube.py --size 10 --shape 4 4 4 --stl ```

A puzzle produced with these settings is provided.

Enjoy :)
