The MultiChain is a chain comprised of a series of ball and socket joints that snap together. On either end of the chain is a piece that can slide onto any 2 cm wide or smaller surface and be secured with two screws. The main body of the chain is made of pieces with both a ball and a socket on each end, and a hook that other tools can be hooked to. More of these pieces(with or without hooks) can be printed to make the chain longer. The "Multi" in the name comes from the fact that it can have multiple uses( portable tool belt, hold back wires, etc).
