Based on http://www.thingiverse.com/thing:9359 and http://www.thingiverse.com/thing:9203 this script allows to model any vertex. Special thanks for WilliamAAdams' work on OpenScad 3d math!
You can use this script to print vertices for creating any wireframe model. The script can accept vectors for all directions the edges have to go. Cut your edges and you have your solid wireframe model.
For fun and pleasure, and for all math enthousiasts, all regular solids are added to the script. See the script for details on how to generate the vertices.
