The Progressive Bracket

Using topology optimization and reverse engineering, I aimed for an ideal shape in this design. A more conservative version is also available. The part's weight is 0.52 lbm (236 g). For load cases 1, 2, and 3, the highest von Mises stresses are 140 KSI (967 MPa), 144 KSI (991 MPa), and 143 KSI (984 MPa) respectively. In order to avoid surfaces with an angle smaller than 45° relative to the build plate, I selected the build up direction. Supports are included in the step file; however, they can be disregarded as they're just a recommendation. The supports weigh 0.097 lbm (44 g).
