I did a course on topological optimization at university which covered pretty much this concept. We used some software from a company called Altair. Essentially you defined some physical constraints and it generated the optimal 3D bracket. The software was seriously clunky, but it has a lot of potential. https://www.altair.com/topology-optimization/ https://www.altair.com/topology-optimization/
