3d-maze-generator

This is a parametric model for a 3D maze. Generates openscad which can render to STL. It uses Prim's algorithm to generate the maze so it has a defined start.

The maze is generated randomly but the start is always on the same face. Parameters like size, diameter, and number of nodes can be supplied. The end is chosen by choosing the node on an outside edge that is furthest from the start.

Installation

Install my version of Solid Python. The official version currently has a couple bugs.

git clone https://github.com/conorpp/SolidPython
cd SolidPython
sudo python setup.py install

Install other pip modules

pip install docopt

Usage

3D maze generator.  Uses Prim's alg to generator maze with
a start and an end and no loops.  Outputs openscad.

Usage:
  maze.py -h
  maze.py [-x WIDTH] [-y HEIGHT] [-z DEPTH] [-r RES] [-n SPACING] [-d DIAMETER] [-m | -s] <output.scad>
Options:
  -h, --help                    Show this help message and exit
  -x --width WIDTH              Number of cells wide [default: 5]
  -y --height HEIGHT            Number of cells high [default: 5]
  -z --depth DEPTH              Number of cells deep [default: 5]
  -r --resolution RES           Resolution of rendering [default: 25]
  -n --node-spacing SPACING     Distance between nodes in mm [default: 8.0]
  -d --diameter DIAMETER        Diameter of nodes in mm [default: 6.0]
  -m --enable-mesh              Creates a cross hatch mesh and subtracts maze from it.
  -s --enable-solid             Creates a solid cube and subtracts maze from it.

Examples:
python maze.py output.scad
python maze.py [-x 10] [-y 5] [-z 4]  [-n 10] [-d 3] [-m | -s] <output.scad>

Running the maze.py program will generate an openscad file. Open this with an openscad version built after 2017. You can find these versions right now by going to the downloads page and going to Development Snapshots.
