Sorry for the late response, I just arrive from holidays.
I think the best way to approach this is to make tsBox primitives (with 3x3x3 edges) for the main shapes and then tsBridge the center faces of each Box sides.........I am just thinking on it without actually testing it on a model........I will try to test it and show it to you as soon as I have time (to many things to catch up after holidays
