A blower housing and method of manufacture includes a wrapper wall sheet conjoined with a first side wall and a second side wall and held together with a seam interlocked with mating protrusions and apertures. The housing design may utilize different types and thicknesses of conjoined materials, allows reuse of the components when separated, and a substantially smooth positive locking seam without the use of welds or fasteners.
