To make LEGO Luke's lightsaber easier to build out of paper, I've divided it into several different, separate easy to build parts.
Although making it as one big hollow shell would make the "polycount" (the number of pieces in the 3D model) much lower, that's often not the best option when you're only making the 3D model as a tool to make a papercraft model! ;o)

This shows how I broke down the dragon plume on the Black Knight's helmet into separate parts, because when I'll make it as a papercraft part, it will be much easier this way than making it as one hollow piece.
Basically, you have the main body, and everything that's thinner (like the tail tip, tail spines and the beak) and everything that's thicker (like the wings) are separate pieces that will be assembled and glued on separately: [link]
Like all of the new units in Advance Wars Dual Strike, the Megatanks for all five armies look exactly the same, except the colours. I'll release the other three Megatanks (Green Earth, Blue Moon and Black Hole) once I've had a chance to build them so I can take some pictures. ;o)
Parts and instructions to build your own Yellow Comet and Orange Star papercraft Megatanks though are already available now from the Advance Wars section on my papercraft webpage: [link]
