Final Design Concept

You should try to present and communicate clearly your final design intention - what you are hoping to 3D model in CAD and manufacture to satisfy your Design Brief and Specification. 

You should present your final design either as a 3D rendered sketch, ideally from 2 view points - one from the front and one from the back, which therefore ideally shows all 6 faces / sides of your designed product OR a series of 2D views showing the Front, Top, Left Side, Right Side, Back, Bottom of your designed product. You can also include a 3D sketch.
