As I bulid my model, this was my plan:
1) I decided to use aluminium as I really do not have time to stay back in school to use the workshops and the aluminium can be cut easily at home.
2) The tesselation I decided was my Set A as I felt that this set was the most suitable one - the other two set was too complicated for me, with lots of lines etc. The set A tesselation also have too much lines and layers and thus I felt that I have to cut down some or my model will be too complicated.
