foot pedal 3d model

Create a realistic 3D model of a compact mechanical foot pedal designed for a laptop cooling system. The pedal should use a simple hinged lever design similar to a sewing machine or MIDI foot pedal and be optimized for 3D printing. Include a strong rectangular base, angled pedal surface, rear hinge mechanism, and a front attachment point for a pull string or linkage system. The design should look durable, compact, ergonomic, and mechanically functional with realistic proportions, rounded edges, and industrial engineering styling. Avoid electronics, wires, motors, decorative elements, or futuristic shapes. White background, centered object, realistic product render.
