I decided to start with a nice, big, chunky shape – the operator’s cab. In order to ensure printability and promote integrity through the life of the model, I chose to exaggerate the walls of the cab. The design should be a little over 2mm thick walls at 1:24 scale. The design has no moving parts but I have placed the roller cylinders in locations that I think best illustrate their function. Without making the doors operable, I created recessed frame lines to denote the door seams. The two grab handle bars will be done later. I will set the cab aside and add more detail later. I am also going to test upload the shapeways and evaluate the results.
