I guess I should have posted a new reply instead of editing the old one, as there is no indication that the thread was updated (last post date). :roll:

So I decided to expand on my original solution. First, here is a better picture with green bars illustrating the solution:

Green bars highlights the intersection


The nice thing about this is it's expandable, and the external silver tetrahedra provide additional sturdiness and support:

Four intersecting tetrahedra

10 intersecting tetrahedra

More to come!

So now I decided to take a more 3-dimensional route and join 3 segments together in a triangular orientation. This form isn't quite as sturdy as the tower:

Here is another angle:

And then there were 4:

4th section added to the bottom of the 3 segments
