This blue hose connector features a simple and practical design with a two-part structure. The upper part has a straight tube-shaped interface, while the lower part tapers off, allowing it to fit pipes of different diameters perfectly. With a smooth surface and rounded edges, it’s ready to use right after 3D printing without any additional processing. It’s ideal for fluid transfer in DIY projects, model assembly, or small mechanical devices. Light yet durable, it’s a great choice for makers and engineers.
