The shark is pretty low-poly and the two pieces have no registration features so assembly is a pain, but I liked the concept. I did the shark at 0.14mm layer height in third-party ABS and the water at 0.19mm in Z-ABS. Acetone vapor smoothing on both.
The photos don’t really do the finish on the shark justice - it is absolutely mirror-smooth and glossy, not a layer line visible. And yeah, the water came out cool too.
