Hey, that will be pretty cool! If you are going the 3d printed route, just heads up, Nerdforgedesign/CGTrader took down the Mark Vb Security shoulder model I'm using. Not sure if any other modeler is offering those STLs. Galactic Armory has a nice Emile helmet file.
I'm really liking the N4+ so far. I do wish Orca slicer had a profile for it though. Right now I am using the N4Pro profile just with a bigger bed measurements. Oh, I should add to the post the time it took to print. I'll need to double check before I edit, but I think it was ~13 hours. I just printed the Gungnir pad, and that took around the same time. All that to say, as of right now, totally worth $350.
