.stl is on github .F3d (the project file with timeline) is on printables (coz of github upload limit of 25mb))
there are 2 arc reactors in this project one is classic proof that tony has a heart and one that has holes for magnets so you can put one piece of it inside your t-shirt and other outside for a cool arc reactor chest piece.
magnet holes are lot more visible in the slicer
