We all love tensegrity, much less the wires fine-tuning so I designed it to have only one wire to adjust.

This model is easy to print and assemble.
Put a central regular support pillar in snug mode. Print 2 pyramids (or squids), preferably with different colors for a better look. The squid is a little bit trickier to print. I added some brim at the feet' base and the central pillar. Be sure not to use a support blocker to not stuff the holes at the base with support. Assemble, break people's minds, and dominate the world.
Assembly:
- Stuff a standard cylindrical N52 magnet (the 15 x 10 mm ones; you can order them here) inside the central shaft of both pyramids
- Take a spacer (other magnets, some simple 7mm cube, whatever), I found 5 to 7mm to be a sweet spot. I added a spacer to help.
- Once there, take some fishing nylon wire (I took some 0.4mm) and make a double or triple knot on one end, guide it through all the holes of all upper and lower pyramids one by on,e and get back in the original hole you started from
- From there, prepare the final double knot and tune it tight to the hole, eventually using the rod of a screwdriver to “slide” the knot along
- If it helps, sometimes, collapsing a tiny bit of the structure at the very last knot adjustment helps to get the tension right.
- I leave mine "opened" but you can print the intersect blocs to fill the gaps in the pyramid base if you prefer
As usual, I'm not responsible if you eat glue, drive over your pet in the driveway, or swim with a weighted belt on.
