      Hi all,
      I have designed a connector looks like the file attaches.
      I want it to be with high bending resistance in the two main axises and also would be light (this is two mm thickness, made as sheet metal)
      With the attached design there is a problem since it can rotate along the diagonal axis( hard to understand i can attach the axis on model if you like).
      Is there any recommendations?

      In order of increasing improvement to stiffness:

      1. Weld corners up. or add a tab an place a spot weld or rivet to lock the corners.
      2. Box the section in with a lid.
      Lid could be attached with rivets or welding.
      A closed section is many many times stiffer in torsion than any open or C shaped section.
