K'nex Not-So-Small Empire State Building

About: Finally back, this time with my new Ball Machine, Helios! If you like it, thanks! Otherwise, thanks anyways for knowing what it is!

Well, I'm back with my largest project ever - the not-so-small K'nex Empire State Building! Standing at plenty over four meters, it couldn't fit in my home, so I had to build it on my balcony. I've entered it in the K'nex contest, so if you really like this, please vote for this. So, let's start building this 4.3 m tall Empire State!

Step 2: Overview

In this instructable, we shall be making four sub-towers :- the red tower, the yellow tower, the blue tower, and the spire. Each of them has a similar structure, except the spire, which is slightly different.

Step 3: The Red Tower

The 3D Blue connectors are there on the top only because I ran out of 3D Greys.

Step 4: The Yellow Tower

The lower Blue connectors in the base are necessary, but not the ones in the modules.

Step 5: The Blue Tower

Please note the angle of the 3D Grey Connectors, otherwise they won't connect properly with the rest of the tower.

Step 6: The Spire

This sub-tower, for some reason, reminds me of a rocket.

Step 7: Assembly

The assembly is the reason why the 3D's on the base had to be angled. Congratulations on creating the (*ahem*) Empire State tower! Give yourself a pat on the back!

    Pparshan, its a good decorative idea, but not as fun or useful... Still, its awesome.

    Sorry, got a little confused with a colony in our neighbourhood ( Empire Estate). And I personally think that 'Empire Estate' sounds slightly better.....
