Horga'hn Idol from Star Trek. Vertically sectioned, no supports

I liked TimStough's remix of Mrcleanr6's Horga'hn model, but I wanted to align the layers with the 'carved' tool marks, avoid supports, and fit the model into a short & squat printer. The poly count has been further reduced, and a cavity has been added to the top, reducing the filament used and lowering the center of gravity.
I was able to generate gcode for this model in slic3r on a moderately provisioned pc with some auto-repaired errors, but without timing out.
