powered respirator 3d model

Create a modern, ergonomic 3D wearable face mask designed for medical-grade plastic or soft silicone. The mask fully covers the nose and mouth, with smooth organic contours that naturally fit the human face and evenly distribute weight for long-term comfort. Include discreet side clip or rear anchor slots on both sides of the mask to attach an adjustable elastic head strap. The attachment system should be smooth, rounded, and easy to attach or remove, with no sharp edges. Add a motorized airflow system with a dedicated mounting area on the front or slightly side-angled section of the mask, compatible with a 2 inch × 2 inch, 5V DC motor fan. Place a protective internal plastic mesh or grille between the fan and the nose to prevent contact, while maintaining smooth, low-noise airflow toward the breathing area. Design an external housing for a 6-inch HEPA + activated carbon filter, positioned on the outer surface of the mask for maximum air intake efficiency. Ensure the filter connects
