SCAFFOLDING WRAPPING A BOX

Hello all,
I'm new to GH and I would like to ask some help to design a spatial grid that wrap up a box or any other shape.
Basically I need to repeat a module –designed in Rhino– of dimension 2x2x1 meters to generate what is a very simple scaffolding. I attach few sketches to make it clearer!
What I've achieved so far is nothing and I'm not able to control the module avoiding distortion.
If you can give me some tips as to how I should do this, I will really appreciate it. Thanks!
