Wanted Decent Ironman MK43 or MK45 stl helmet and armor files

Hello fellas and gals
real quick does anyone know where to find good tested Iron man helmet and armor stl files. The helmets are to be honest everywhere but am wanting some guidance on a good relatively accurate tested 3D file or should I say files for the armor . There are so may Variations just looking for the basic red and gold version like the MK43 or 45. Or what ever else you folks recommend.
Thanks Jerry
