paint brush holder 3d model

Use simple geometric primitives (cylinders, cubes, filleted edges). Avoid complex organic surfaces. Create a clean, watertight, manifold 3D model of a paint brush holder designed for FDM 3D printing. The model must be: Fully solid and manifold No holes, gaps, or non-manifold edges No floating geometry or intersecting meshes Clean topology with minimal triangles Optimized low-poly mesh suitable for slicing Scaled in millimeters Export as a clean STL file Design specifications: Desktop paint brush holder organizer Cylindrical container design Base diameter: 100mm Height: 120mm Wall thickness: 3mm Thick stable base (minimum 6mm) Smooth rounded edges Minimal modern design Functionality: Interior must hold multiple paint brushes upright. Internal space should fit brushes up to 10mm handle diameter. Interior depth at least 100mm 3D printing requirements: Flat bottom surface for strong bed adhesion. No supports required. Overhangs must not exceed 45 degrees. Designed for printing at 0.2mm
