The problem with availability of stl file (noted by previous reviewer) was promptly and easily solved by contacting the designer. Everything is fine now. Recommended: This model of Drepanaspis captures the fish's details and design very well. I encountered no difficulty printing the model in its original stl size. At larger sizes (e.g., 20cm = life size), I had some issues with the resin splitting or developing a distinct horizontal line - this may have been caused by the abrupt change in cross section between the head and tail (i.e., sudden change in stress on the resin). Success of large prints was best when the model was oriented at an angle with the head closest to the build plate. I also hollowed out the model (to save resin and reduce weight) and added drainage holes.
