Tech Lego Open Scad Version

Try out OpenSCAD, a free CAD software for creating tech LEGO designs at http://www.openscad.org/. I'll create various sizes for your project; however, generating 12x12 models might slow down your system. To optimize performance, consider working on your laptop and ensure the file size is compressed to avoid large file issues. If you have a specific size in mind, feel free to request it, and I'll do my best to create it for you.
