Abstract: A non-transitory medium having machine-readable instructions stored thereon is provided. The instructions include reference-object code to print a three-dimensional object in a coordinate system of a printer. The three-dimensional object includes a first loop portion comprising a length of a cylindrical body that extends arcuately between spaced apart ends thereof in through each axis of the coordinate system. A second loop portion comprising another length of the cylindrical body extends arcuately between spaced apart ends thereof through each axis of the coordinate system. The second loop portion is opposing and coupled with the first loop portion by respective curved leg portions of the cylindrical body to define a continuous loop that circumscribes a virtual axis thereof aligned with a layering direction of the printer. Each portion of the cylindrical body is asymmetrical with respect to each other.
