Habiton is a 3D-printed nesting aid for wild bees. Made of ceramic, the elements can be expanded modularly and installed ideally in urban areas. In this way, species threatened with extinction are optimally promoted. As part of the global ecosystem, humans depend on the survival of bees and should try to support wild bees in both private and public spaces. Habiton is the first nesting aid designed to be used theoretically for thousands of years, using only local natural raw materials.
