Universal Cleaning Brush

A strong, general-purpose 3D printed scrub brush designed for cleaning tools, dishes, bike parts, and shop surfaces. The model prints flat with no supports using a standard 0.4 mm nozzle. The bristle pattern provides stiff scrubbing performance right off the printer.I have printed multiple brushes in PLA and they have worked well for general cleaning. Different materials can produce different bristle characteristics — PETG offers more durability for wet or hot environments, and nylon or PETG-CF can make the bristles even stiffer.
