Bracket for Rocket

An internal boattail support bracket for Atlas V rocket per the ULA 3-2-1 challenge specifications. Emphasis on this challenge entry is on uncomplicated 3D printing with minimal need for support structures. The part is printed in design envelope Z-direction. Support structures may still be needed for holes “D” and cylindrical cuts for “washer flats” for lower pair of these. These should be quite easy to clean up with a bore. Emphasis is also on ease of installation with plenty of room for tools. It is assumed that 0.6 in diameter groove is helpful for installation. Part mass exceeds target (0.1 lb) somewhat to ensure proper structural strength. Mass: 0.1825 lb Volume: 3.7703 in^3,(82.79 g, 61.78 cm^3, density 1.34 g/cm^3)
