_Take your binge drinking to the same dimension!_ This immersion of the Klein bottle in 3D space has a modified bottom which acts as a bottle opener. The cutouts on its surface allow a view of its self-intersection while keeping the model easy to print and contributing to its overall organic shape. The Klein bottle is non-orientable, closed, and has no boundary. It lives in 4D space, but we visualize it as an immersion in 3D space. Its non-orientability means an object moving along this surface ends up at its starting point flipped upside-down and mirrored. It was first described by Felix Klein in 1882.
