Abstract: A variety of interlocking links can be connected to each other and to cylindrical or other shaped tubes. The links incorporate features that may facilitate removably connecting multiple links to one another and removably connecting links to tubes at a wide range of angles to form a variety of multi-dimensional shapes, while obviating the need to use tape or glue.

Abstract: A variety of connectors can be used to connect cylindrical or other shaped tubes to one another. The connectors incorporate features that may facilitate connecting the tubes at a wide range of angles to form a variety of multi-dimensional shapes, while obviating the need to use tape or glue. Such features can potentially improve the aesthetics and simplify the assembly of objects produced using the connectors. Further, structures produced using the connectors can be disassembled, facilitating reuse of, for example, the paper-based tubes of exhausted household products.

Abstract: Paper cylinders or tubes may be connected to one another using any of a variety of connectors. The connectors incorporate features that may facilitate connecting the paper cylinders or tubes at a wide range of angles to form a variety of two- and three -dimensional shapes, while obviating the need to use tape or glue, thereby potentially improving the aesthetics of objects produced using the connectors. Further, objects produced using the connectors disclosed herein can be disassembled, facilitating reuse of the paper cylinders or tubes.
