Grasshopper geometric structure required

hi, i've modeled a building in rhino, its a box with some surface manipulation and i need it transferred into grasshopper and a geometric structure to be created so i can print it on a 3d printer,
my models going to be 1:100 and can be 3mm in thickness, i need a horizontal and vertical rib pattern to depict a possible structural viability of the model,

in the attached files the first and second image is my model, and the next three are what i'd hope fully like to achieve

i have more image examples, and i also have a auto cad model, rhino 3d and sketch up and 3d studio max version of my model, so i can forward it over in any format.

i look forwards to speaking to you about this

thankyou for you interest

best regards
