Oh!Carina is a fluid mixer exploiting two, or more, internal cavities. The mixer doesn't need to be assembled, instead, is made of a single piece made with 3D Printing Technology. In fact, the cavities couldn't be realized without additive manufacturing technology since the undercuts of the shape.
Internal tanks were designed in such way that liquids don't come out when filled horizontally from the two openings.
When the object is raised vertically the liquid comes out from a bottom opening mixing together. Realizing the object with 3D printing allows it to be reproduced in various scales and capacities responding to the needs of for different applications.
