Eugenio Costa’s Omnibite joint connects raw branches without screws

Eugenio Costa, a product designer from Milan, has created Omnibite, an innovative three-axis joint featuring a quick-lock mechanism that connects raw branches without the need for screws. This design allows natural materials to serve as structural elements with minimal setup. The joint can accommodate various diameters and angles using clamps and interlocking plates, framing construction as a balance between precision and irregularity. Rooted in research on local wood species in Lombardy, the project views the landscape as both a resource and a source of knowledge. Costa’s method transforms self-building from merely assembling pre-made components to working with materials as they are found, resulting in a chair crafted from available branches. The joint system integrates metal and 3D-printed components into a modular connector.
