fish 3d model

Create a 3D-printable master model for a plaster slip-casting mold. Show a fish from a true top view, as if seen from above through water, not from the side. The fish must have an elongated, elegant, minimalist shape. Use only the essential forms: long body silhouette, tail fin, and simple fins. No eyes, no lips, no scales, no texture, no facial features, no small details. The underside must be completely flat. The top surface should have low smooth relief with soft rounded transitions. Avoid undercuts, deep grooves, sharp edges, and thin fragile parts so the model can be removed easily from plaster. Add slight draft angles for clean demolding. Include a simple rectangular formwork box around the fish with enough margin for plaster.
