nebulizer mask 3d model

Create a professional 3D model of a medical oxygen nebulizer mask optimized for Blender and Autodesk 3ds Max. Modeling Style: * Clean subdivision-ready topology. * Mid-poly production model. * Base mesh between 2,500 and 5,000 polygons. * Quad-dominant topology. * No N-gons. * Suitable for TurboSmooth, OpenSubdiv, and MeshSmooth modifiers. * Watertight mesh. Reference Shape: The mask follows an ergonomic adult oxygen mask design with a vertically elongated teardrop silhouette. Dimensions: * Height: 110 mm * Width: 85 mm * Depth: 55 mm * Shell thickness: 1.8 mm Topology Requirements: Main Mask Shell: * 20–24 edge loops around the perimeter. * 12–16 loops around nose bridge area. * 8–10 loops defining cheek curvature. * Rounded transition surfaces. * Smooth anatomical contours. Ventilation Holes: * One circular hole on the front center. * Diameter 14 mm. * 16-sided circular topology. * Supporting edge loops around opening. Side Vents: * Two elongated oval holes. * One on each
