Prompt
Create a simplified shrimp-shaped 3D part, hollow inside, designed for two-part molding. Units: millimeters. Scale: 1:1. Axes: X = length (head→tail), Z = dorsal/up, origin at geometric center. Target outer size: total length 90 mm, max width 28 mm, max height 18 mm. Wall thickness: uniform 2.5 mm (tolerance ±0.2 mm). Outer geometry: gentle “C” curve (smooth), 7–8 shallow shell segments (0.6 mm grooves), a subtle dorsal ridge; no fragile appendages (omit long antennae/legs/eyes). Short rounded rostrum. Interior: continuous smooth cavity preserving 2.5 mm wall; no sharp internal edges. Molding intent: set parting line on the YZ plane, splitting left/right halves (minimize undercuts). Apply draft angles of 2.0° on external surfaces and 1.0° on internal surfaces, pulling away from the parting line. Process features: add one injection gate/sprue (Ø4 mm) on the ventral side, 20 mm from the head tip, entering radially into the cavity (with inlet chamfer). Add two air vents (Ø1.0 mm) near the tail end (symmetrical), connecting cavity to outside. Fillets & finish: minimum fillets R0.8 mm outside and R0.5 mm inside; overall smooth surface (low noise) while keeping the shallow ring grooves. Mesh constraints: watertight manifold mesh, no self-intersections, no inverted normals, no non-manifold edges. All normals outward. Resolution: sufficient tessellation to capture 0.6–0.8 mm radii; avoid unnecessary over-triangulation. Output: a single hollow solid STL, oriented with length along +X and back along +Z, ready for mold split operations. Exclude: no bases/supports, no inserts, no embossed text.
