Skull Pile for Warmachine Cryx Wraith Engine

I needed a base that was more interesting for my friends machine wraith. This skull pile looked great, but I wanted more skulls, and to turn them all to hide the flat unfinished bottoms of the skulls. I took the time to size it for the 5in base, and to hallow it for easier printing. I have not sliced and printed the model yet, but I am doing that now on my ANET A8.
