I think that once Zabana is done with the forearms there might be a possibility for a zip file with all suit parts. I'm not sure if the armory will be in the same zip file or a different one. As for the scaling, no its all at different scales... so when you rescale the parts you need to, Pepakura Designer will scatter all the parts again and you might need to trim some down to fit the page :/... I tried to scale the leg parts to the same scale of the previous War Machine .pdos. Hope it helped.
BTW Zabana, are the hand plates going to be with the forearm or a file on their own?
And thanks to everyone for the positive feedback on my progress
but its not done yet so it could only mean more updates
for the moment i'm working on unfolding ironmansuitmk6's gatling gun and arm files so keep an eye out for that
