Airplane Bearing Bracket for challenge

My submitted entry is for the Bearing Bracket Challenge. Upon analysis, I determined that this part mainly functions as a bending beam. To minimize stresses, it's crucial to maximize the moment of inertia while minimizing weight. The optimal choice is an I-beam cross-section, which positions material farthest from the neutral axis for maximum benefit. To enhance design efficiency, multiple FEM simulations were executed. Maximum stress levels are below the material's yield threshold for all but one load case - where it reaches 1060 MPa in a small bracket area only. The print direction is from Datum A, and the total mass clocks in at 321g.
