Update: I've finished modeling the ARC Armour and helmet, and I am in the process of assembling another test build with the final shoulder model. I hope this is the last test build. I have a few tweaks to make yet but overall it is going quite well.
I've assembled all of the 'bits' and put the helmet together. Frankly, I was concerned with this one, as it is the smallest complex assembly I've designed (or put together). It has a diameter of about 5mm, with an final width of about 7mm. Overall I think it worked phenomenally. I hope to put the rest of test figures and armour together starting tonight and post pictures maybe by Wednesday. For now, here is a sneak peek at the helmet, by itself, with a Canadian penny for scale, and placed on the first ARC prototype figure. Obviously, it is not yet textured, and is missing the clear face shield.
