About this 3D model

THIS TWO PART, SNAP TOGETHER, ABS SHELL IS THE EXTRAPOLATION OF THE SMALLER VERSIONS PREVIOUSLY PRESENTED.BECAUSE IT IS TOO BIG TO BUILD IN EITHER OF THE TWO DIMENSION, 3d PRINTERS, THE NEXT STEP WAS TO "CUT THE PIE" IN FOUR (4) WEDGE SHAPED SEGMENTS AND DO FOUR PRINTINGS. ACTUALLY EIGHT (8) WITH FOUR INNER SHELL SEGMENTS AND FOUR MORE OUTER SHELL PIECES.
