Gyroid Construction Set
The Gyroid has got to be pretty much my favorite mathematical shape, what with all its complexity yet surprising order and periodicity. With the ancestor of this thing, I finally figured out how to print one well without support on a cheap 3D printer. Now I've figured out how to connect them together, which makes them vastly more useful and interesting.
These little wiggly connectors actually screw into the gyroid modules and hold them very stiffly, especially once you get several going though in different directions. Check out the video to see my explanation of the assembly process: http://youtu.be/lIqKSJxahmc
The sky's the limit on what you can build out of these modules. Show me some sweet "I made one" pictures of your creations!
