Quelaag, the Chaos Witch from Dark Souls! Typically, I don't like to print models or post models in pieces, but for her, I had to do it this way to make her print to my satisfaction.

The model parts should be printed at the following %'s if you are aiming to print at the same size as the one in the picture:

For the human body, print at 500%
For the DS boss base, print at 500%

For the main body and all legs, print at 2200% (or 2000% if you want the human body to stand out a little more).

Note: Added the .stl for the complete model and the complete model including the DS:BG base if you want to give that a try.
