This is the SC-37 helmet from the game Helldivers 2
The file set comes fully split up for easy printing
Base scale fits about a 23 in head circumference
has an optional swap out plate to either run the plastic VR front plate or to allow for a vacuum formed visor to be put in its place to be able to see out the helmet.
The file set includes a visor buck for this or a visor can be purchased from my website

Happy making and let me know if you have any questions or issues with the file set!
