Leviathan Configuration as seen in Hellraiser2. The pattern is done via negative parts and will be recessed when printed. I used movie stills and information I could find online to attempt to match the pattern, proportions, and scale. I used a .2 nozzle for crisper detail. Print two and glue them together, but note that the pattern doesn't line up exactly, I rotated the halves until I got a close enough match.

For the glowing effect, I use TechnoGlow blue glow in the dark paint. After several minutes out in sunlight, it really does glow that intensely.
