i think that I’ll try using two staggerered aluminum flat pieces as the long brace. I’ll drill holes about an inch apart so I can adjust the length . It will be easy to collapse also. I see a lot of versions based on your photos. Thanks for the prototype and idea.
i think it would be great to have kids build some with plastic containers on the top and bottom and either spray paint them or cover them with wood grain contact paper. A cheap, quick and not many tools required youth project.
