The arms, head and body are in seperate pieces to facilitate painting.The body is comprised of multiple parts so if you are using Simplify3D to slice make sure to use the Seperate Meshes option to slice it properly. Most other slicers can slice it i just fine.The arms are the same so just mirror in your slicer. I suggest printing them with the elbows facing up so that the support matterial is on the inside of the arm and any artificats are hidden once putting the figure together.
