3D STL model of a tubes distribution manifold with 4 tubes, ready to use in your projects. This cross-style model offers 4 tubes, spaced regularly by 90° around the center. Each branch is sized for tubes with an outer diameter of 28 mm and an inner diameter of 25 mm. This thickness (1.5 mm) corresponds to a thin wall. Internal end fillets improve the insertion lead-in and reduce the risk of aggressive burrs. This part could suit extraction systems, air-cooling setups, or any project where a flow has to be routed toward several outlets.
