1. A three-dimensional article produced from sheet material, comprising a frame unit defining an interior and having a plurality of outer sides made of sheet material each having a different angular disposition, wherein first and second longitudinal ends of said frame unit are interconnected by means of a female fastener embedded in said first longitudinal end and a male fastener introduced through said second longitudinal end and coupled with said female fastener, wherein the first longitudinal end of the frame unit comprises a first side flap formed with at least one first aperture, said first side flap being folded and affixed to a base portion of a frame unit side such that said female fastener when placed on a predetermined region of said base region is embedded within said side flap while being accessible to said male fastener by means of a corresponding aperture,wherein the second longitudinal end of the frame unit comprises a second side flap formed with at least one aperture, said second side flap remaining in an opened position while its at least one second aperture is aligned with said at least one first aperture and said male fastener introduced through said at least one second aperture is coupled with a corresponding embedded female fastener, whereby to form a reinforced connection,the frame unit further comprising a plurality of exterior members, each of which is interconnected by means of a reinforced connection, wherein each exterior member comprises a base portion, a flap inwardly extending from said base portion, and at least one extension outwardly extending from said base portion and provided with a single projection protruding from an outward edge thereof, a first portion of said inward flap being adhesively affixed to said base portion and a second portion of said inward flap being foldable perpendicularly to said base portion. 2. The article according to claim 1, wherein at least one expanded stabilizing element is frictionally engaged with inner faces of the frame unit, for increasing the structural strength of the three-dimensional article. 3. The article according to claim 1, wherein the reinforced connection protrudes from an inner side of the frame unit. 4. The article according to claim 1, further comprising an insert made of the sheet material, the insert being located within the interior of the frame unit and contacting each inward flap second portion of the frame unit. 5. The article according to claim 4, further comprising a reinforcement adhesively attached to the base portion of each exterior member, an outwardly folded peripheral element of the insert being positioned within spacing between said reinforcement and a corresponding inward flap second portion. 6. The article according to claim 4, wherein a plurality of apertures are formed in the insert and the extension of each exterior member is inwardly folded until the projection protruding from its outward edge engages a corresponding aperture formed in the insert, thereby concealing a corresponding reinforced connection. 7. The article according to claim 1, wherein a first exterior member comprises two side flaps that are folded and adhesively affixed to the base portion, two female fasteners being embedded in each side flap and being accessible via a corresponding aperture formed therein, and a second exterior member comprises two side flaps each of which are in an opened position and bored with two apertures, a male fastener introduced through a side flap aperture of said second exterior member being coupled with a corresponding female fastener embedded within said first exterior member to form a reinforced connection. 8. The article according to claim 1, wherein each exterior member comprises a first side flap that is folded and adhesively affixed to the base portion, two female fasteners being embedded in said first side flap, and a second side flap that is opened and bored with two apertures, a male fastener introduced through a second side flap aperture of a first exterior member being coupled with a corresponding female fastener embedded within a first side flap of a second exterior member to form a reinforced connection. 9. A three-dimensional article produced from sheet material, comprising a frame unit having a plurality of outer sides made of sheet material each of having a different angular disposition, wherein first and second longitudinal ends of said frame unit are interconnected by means of a female fastener embedded in said first longitudinal end and a male fastener introduced through said second longitudinal end and coupled with said female fastener, wherein at least one expanded stabilizing element is frictionally engaged with inner faces of the frame unit, for increasing the structural strength of the three-dimensional article, andwherein two stabilizing elements are interconnected by means of a notch formed in each of said two stabilizing elements. 10. The article according to claim 9, which is a cabinet, wherein a first stabilizing element is a spine member and a second stabilizing element is a shelf element, a web of said spine member being formed with a plurality of parallel notches formed only in an outward region of said spine member web by means of each of which a web of a corresponding shelf element is interconnected, expanded flange portions of said spine member and said corresponding shelf element being frictionally engaged with corresponding inner faces of the frame unit. 11. The article according to claim 10, wherein a cabinet back is formed with a plurality of apertures and each exterior member of the frame unit comprises an extension outwardly extending from an inner face of the cabinet back and provided with a single projection protruding from an outward edge thereof, said extension being inwardly foldable until pressingly contacting a corresponding frictionally engaged flange portion and the projection thereof engages a corresponding aperture formed in the cabinet back. 12. The article according to claim 10 which comprises a plurality of second stabilizing elements which are shelf elements, wherein each shelf element comprises two U-shaped appendages that protrude from an inward edge thereof, said appendages being adapted to be introduced in corresponding slits formed in a cabinet back and foldable so as to contact said back, a clip having two parallel portions being insertable in a slit such that one of said parallel portions pressingly contacts a corresponding folded appendage. 13. The article according to claim 1, which is selected from the group consisting of cabinet, table, storage box, wheeled storage box stool, doll house, chair, trunk, bench, wine holder, and file holder. 14. A kit for assembling a three-dimensional article, comprising a plurality of separate members made from sheet material and set in a flat condition, including one or more first members configured with a side flap in which is embedded at least one accessible female fastener and one or more second members configured with a side flap in an opened position formed with at least one aperture, wherein a male fastener introduced through an aperture of the opened side flap of a second member is coupleable with a corresponding and aligned embedded female faster of a first member, so that when a plurality of said first and second members are serially interconnected such that each of which has a different angular disposition a frame unit is formed, wherein a first or second member comprises a U-shaped base portion, two divider elements stacked in a flat condition and overlying a centrally located, rectangular open region of said base portion, border flaps that border said open region, a foldable side flap extending from a first divider element adhesively affixed to a first border flap, and a foldable side flap extending from a second divider element adhesively affixed to a second border flap, wherein said first and second divider elements are foldable so as to be perpendicular to said base portion and unattached side flaps of each of said first and second divider elements being interconnectable with corresponding unattached side flaps of folded divider elements of an opposed member of the frame unit. 15.
