Abstract: The present invention involves the creation of a self contained multipurpose monolithic structural body. The invention eliminates the need for the use of multiple pieces in the manufacture of vehicles, automobiles, aircraft, spacecraft, engines, homes and other items of manufacture, thereby causing the entire item of manufacture to be one unit. The viscus of the unit contains conduits through which necessary wiring, mechanical parts, fuel, coolant, air, gases and other fluids pass. The invention simplifies the current hazards associated in the manufacture of items, by eliminating the use of multiple pieces and thereby decreasing the likelihood of failure of an individual part which often leads to failure of the whole. Moreover, because the invention is monolithic and self contained, the invention reduces the cost of manufacturing items, increases structural strength and integrity and reduces the structural weight of the item manufactured.
