This is 3 of the previous tensegral units,
joined together to become a mast.
If this kind of thing interests you, like this, and follow me, because I'm going down a tensegrity rabbit hole!
This one was a pain to lace up, and in hot gluing up the tension lines, some slipped/stretched and are slacker than I'd like. Ahh, beware irreversible steps in assemblies.
The supports have cut outs so that you can stack them (each requires a bit of rotation), then I put a bit of hot glue on each joint to secure it all for lacing. You don't have to join every possible node, but some are critical. I may make another that is simpler to assemble, this one is a bear.
