[Update]: Added 3 more flat options with more angularity and less structure (4-6). The shown minimal structure will bend, but has a great effect if done well. 0.4mm (26 gauge) wire works great!

:::For added effect, only wire three of the connections as shown. Don't do this for the 2-part, unconnected Flat 6 base. Be careful to keep the weight TOWARD the NON-WIRED side or it will tip:::

A tensegrity display table with options for top and bottom sections. Banana for scale.

I used 1mm craft wire for the pictured silver model, but I recommend finer wire or strong fishing line. Wire allowed for substantial strength and longevity while avoiding complicated knotting and tying of string. The print itself can certainly be improved with setting changes.

Arcs fit firmly into slots in each flat section. Use force.

For the easiest assembly, tie the centers of each arc together first, then attach one base and make ties of equal length. You will need to tighten these well to prevent wobbling or distortion of the strings/wires when weight is added.

Wires or strings extend through the structures for strength and to ease the tying process.

Arcs are 8mm thick so I recommend a top/bottom thickness of 4+ mm to make the arcs solid. All holes are 2mm in diameter with 1mm of depth on the "outside" of the parts, so use 1mm or smaller wire. 0.4mm wire or strong fishing line will enhance the illusion so long as the weight is limited. Remember, most of the weight will be held by one strand. The arcs are very strong, so the string is the weak link.

If the holes print closed, heat a paperclip and poke through. It should only be a very thin layer.

Comment if you want CAD files. A few are messy, but they're all adaptable.
