security bollard 3d model

**Final 3D Model Prompt — Bollard System with Solar Panel & Control Panels** > Create a realistic **3D model of an automated retractable security bollard system** used for vehicle access control. The model should include a **cylindrical stainless-steel bollard** with brushed metal texture, subtle scratches, and a reflective finish. Show the bollard in both **raised** and **retracted** states. > > Include the **underground housing chamber**: concrete casing, hydraulic piston mechanism, internal wiring, drainage holes, gravel layer, and a motor unit. The top surface should be a **textured asphalt/concrete road** with a precise circular cutout where the bollard rises. Add a **rubber sealing ring** around the opening and **yellow/black hazard stripes** near the top of the bollard. > > Add realistic components: > – Hydraulic actuator and piston rod > – External control box with visible cables > – Proper scale and separated parts for clear engineering visualization > > **Add three control p
