Sketch model

With great difficulty I managed to cut out a 'spiral-esque' shape using a jigsaw. It is very rough but I just wanted to get a visual of what my final model may (or may not) look like. 

This is very rough but this is what I want my final to look like, except neater. I will also have more spirals because this is very simple. Also I may have 2 spirals and then twist them together so that they are twirling around one another which will make the model more interesting.
