I found this shape quiet hard to make, although the choice of wire helped as I chose a wire that was very malleable. However connecting everything became a very hard task, I asked my tutor for advice on this and they suggested soldering them. So I taught myself how to do that, but making this model I used galvanised wire which doesn't solder unless its sanded, so I spent an unnecessary amount of time doing that when I could have just bought a different kind of wire like I ended up doing later. So this model is a little rougher than the others. 

I didn't chose this model because its the original shape and I wouldn't get a very dynamic building from this.
