Mass = 403gr Mass reduction = 80.4% Pushing the limits of this topology to get the lowest weight possible. Thanks again to Grabcad and GE for putting on this most challenging of challenges, I've learnt a lot about structural optimization tools along the way. Brings back memories of my university days. I've added a couple renders of earlier versions I was toying with, some proved too weak or had wall thickness of less than the requirements. Added an ultralight version to push it down to 397gr, not fully tested.
