Hello all. I have been searching for a print ready volcanic and it appears their aren't any. I found the original file on google sketch up. The owner and file can be seen through this link.

I converted the model into more of a solid in cad and split it up into 4 easy prints. The model appears relatively accurate, but I cannot confirm this. Hope you enjoy. Be sure to most a make if you decide to print it.
