I couldn't find any 3d files to print the belt and the shoulder piece so I made them myself. I used this as a reference image. (http://vignette1.wikia.nocookie.net/fallout/images/8/88/Vault_101_Back.png/revision/latest?cb=20101214205943) Enjoy and tell me if you have any problems with it :D I am will be making this and wearing this and I will update the pics of the pieces and rest of costume. Print of the belt piece (2x3rectangles, beltbucklefront, backofbeltfull [or you can use backofbelt 1 & 2 for smaller printers]) To make the belt you can use black webbing with a buckle. Glue on the right amount of rectangles for your waist (the rectangles are 2 inches wide, the back is about 8 inches wides and the front part is about 4.7 inches just do the math to match your waist) To make the shoulder piece you can either simply paint on the suit a strip of black then attach the printed shoulder pieces or you can get fabric/webbing that is about 1.7 inches wide and glue the printed shoulder piece on that.
