4k Seamless Sci-Fi Greeble Textures with Color and Normal Maps

Here is the first set in a collection of seamless 4k sci-fi greeble textures donated by a gentleman that goes by Mr. Spacehead.  They were donated at 8k but I currently struggling with hosting them that large, so here's a 4k set!  The color and normal maps are included for quicker use in 3D modeling software like Blender or Blendswap.
