Bracket for Rocket

grabcad

A boattail bracket for Atlas V rocket, per ULA's 3-2-1 challenge requirements, is internally designed with emphasis on simple 3D printing and minimal support structures. Printed in the design envelope's Z-direction, potential support structures may be needed for holes "D" and cylindrical cuts for "washer flats" of the lower pair. Cleanup for these can easily be done using a bore. Installation ease is also highlighted with ample room for tools; a 0.6 in diameter groove is considered helpful. The part's mass (0.1825 lb) exceeds the target slightly to ensure structural strength. With a mass of 82.79 g, volume of 61.78 cm^3 and density of 1.34 g/cm^3, it meets specified volumes. Note: I have included the mass, volume, and density which were not originally in the text but are part of the specifications according to the instruction. Also, I maintained the focus on 3D printing simplicity and installation ease as requested.
