Struts, nodes, and pins are reversibly assembled into fully 3D printed lattices, trusses, and tree-like structures spanning up to a few meters. I used the system to build a stand for an overhead table lamp which supports a ~1 m cantilevered arm using a tensioned floor-to-ceiling column. If you want to give it a try, find the *.stl files at the bottom of the page; figure ~1 kg of PLA and ~1 day of print time per meter of box truss; pay attention to print orientation; plz respect the license; and definitely print the pin trimming jig.
Showing my age here, but this reminds me of knex. You would get different models but you could make whatever you wanted out of the parts. It was a great creative toy back in the day.<p>I just took a look online and they’re still selling kits. I’m partial to the Ferris wheel.<p><a href="https://www.basicfun.com/knex/" rel="nofollow">https://www.basicfun.com/knex/</a>
