This is my attempt at a sculpt of a Reaper Leviathan from the game Subnautica. It took about 3 days. I used the game and image searches as reference. It was sculpted predominantly in Sculptris, I used NetFabb to isolate and extrude the fin sections, and to do the final division for printing. I have not completely finished printing it yet, so I cannot vouch for its viability in that aspect.
*Successfully finished printing the halves, and added pictures of the print.
color fab PLA
used a brim instead of a raft, auto treelike support generated for angles lower than 45 degrees
