This is my design of an internal boat tail support bracket for the Atlas V rocket. It meets all your design specifications. It is a one piece design and it is thick where it needs to be. I have been working on this for a couple of weeks now, it has no silly stuff on it (lol). It has plenty of ribs and fillets to minimize stress concentrations.It harnesses the advantages 3d printing vs 5 machining.actual mass = 0.10 lbsvolume = 2.161 cubic inchesMaximum part weight: 0.1 lb (OK) Minimum wall thickness: 0.040 inches (OK)Ultimate load (due to work platform): 600 lbf applied uniformly in the negative Z direction (illustrated on the envelope drawing) (OK)Required material: Ultem 9085 (material properties below) (OK)Material Properties Ultem 9085 Material Strength Allowable: 4500 PSI Specific Gravity: 1.34 Young’s Modulus: 325 KSI Poisson’s Ratio: 0.41 Non-Dissolvable support materialactual mass = 0.10 lbsvolume = 2.161 cubic inches
