Sure thing. First, start with the main tube – treat it like the main span of a bridge. Keep it straight and strong, but don't over‑thick it; that saves weight. Then add a few support tubes that angle inwards, like truss members. These will carry the load to the ground, just as a bridge’s legs do. Make sure each joint is tight and uses a proper joint design – no loose elbows. Finally, test the whole thing with a bit of flex in a model or computer simulation. If it bends but doesn’t crack, you’re on the right track. Stay simple, stay solid.
