This is the inferno squad helmet from battlefront 2. It is cut into 8 pieces for a 200mm printer. Use the .stl file for splitting for a smaller printers. Most of the files ar in .3mf format because stl files were pretty large. In the full helmet .3mf file all the detail pieces are not meshed together. They can be removed to make a standard tie pilot helmet.
The helmet is wearable. It goes on at a slight angle then rotate.
