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.
