trilobite dorsal spine 3d model

Create a thin dorsal overlay piece of a Dicranurus monstrosus trilobite, designed to attach onto the back of an existing 3D model. This must NOT be a full body part. It must be a slim surface attachment piece. Structure: - Very thin central dorsal ridge (low profile, not bulky) - Segmented narrow spine plates along the ridge - Thin lateral spines extending outward from each segment - Two slender upward antenna-like spines at the top - Slight backward curvature following a trilobite back contour IMPORTANT PROPORTIONS: - Extremely low thickness (like a shell plate) - Maximum base thickness: 1.5–2 mm - Spines thin but slightly reinforced for resin printing - No internal volume - No legs - No head - No tail fan - No underside body mass Back surface requirements: - Flat or slightly concave surface for gluing - Clean attachment surface - Smooth inner side Front surface: - Organic exoskeleton texture - Fine segmentation detail - Sharp but printable spines This is a decorative dorsal spine attachment, not a fu
