split tech helmet

Hello this is my first time splitting any kind of model, but I just tried to keep it simple and easy to print. I've heard that for this helmet you should up the size to 120%. for the detail pieces you'll want to scale them up to 120% to match the size of the helmet. Sorry if all that information wasted your time but I've never actually printed this out, so I don't know lol. Also some of the files are obj because i forgot to save them as stl files but it will all print the same and as far as i know if you just treat them like stl's then they will work. The original design for this helmet is by jace1969.
