ergonomic wrist rest 3d model

Create a 3D model of a small ergonomic wrist rest designed for computer mouse use. The object is made of smooth matte black plastic and has two raised curved pads that support the wrist and palm. The shape is symmetrical along the center, with a slight curve and a narrow middle section connecting both pads. The top surface is softly contoured for ergonomic comfort, while the underside is flat for stable placement on a desk. Dimensions: approximately 3.9 inches (10 cm) long and 1.7 inches (4.3 cm) wide. The design should look minimal, lightweight, and realistic, suitable for product rendering or ergonomic analysis.
