The file 'UNSC Name Badge 3D Printer Model' is (stl) file type, size is 131.7KB.
Based on Commander Keyes' name badge (you know the one - it's an easter egg in Combat Evolved that says "Hellomyname Keyes").
Pictured is my personal tag. Published file only has UNSC so you can add your own mission/ship and name to the tag.
