Spacer for a manufactured structure

A method of forming a molded structure, comprising:

• placing materials into a mold;
• placing at least one spacer into the mold, the at least one spacer comprising at least two pairs of opposing legs, each of the legs comprising an elongate member that extends from a proximal end to a distal end thereof, the proximal end of each of the legs connected to one another at a central point such that the legs are spaced radially about the central point substantially equidistant from one another, and the distal ends of the legs comprising a material that has a predefined melting point such that the distal ends attach to a respective surface of the molded structure in contact with the distal ends responsive to the predefined melting point being reached during a rotational molding process;
• and
• initiating the molding process so as to form the materials into the molded structure such that the at least one spacer is located within a cavity of the molded structure and such that the at least one spacer provides structural support to the molded structure by adhering to different surfaces of the molded structure during the molding process by said predefined melting point being reached, the different surfaces of the molded structure defining said cavity.
