that looks awesome jonniemac!
would you share your model for that? i started playing around with cad 123d design and would really like to see how to construct such a thing and later print it as well, as my first 3d printcant think of a better application for a 3d printer...
I've released the .stl files for the basic mod so others can print it at home and they can be downloaded from links you'll find here.
I'm not releasing the working cad files or .stl files for any of the other designs. Sorry.
