Tensegrity Table with swappable Top

I created this tensegrity table as another engineering challenge for myself. I've always thought these tables were a fun demonstration of outside-the-box thinking. Supporting a weight normally involves a compression-type support, but doing it in tension is a fun idea. 

The table holds a full soda can without stressing. You can adjust the height of the table some, use 3 links in the center for a more stable table, and use 2 links for a taller, but less stable table. One link should also work if you are careful with your outer chain adjustments. 

The top is a floating insert that you can swap out with your own design to add a cool icon or color.

The soda can is included in images for scale, and demonstration of strength.

The chain attaches with eye bolts for easy tension adjustment. 

Assembly instructions:

1: Print all the parts. (Print the plate with the base twice. )
2: Screw the 10 eye bolts into the 2 bases (5 each). The 4 outer bolts only go one way. The center eye bolt should be facing the square of the base. Do not tighten the eyebolts past a light snug.
3: Assemble the chains. The table in the picture has 7 chain links on the outside and 2 chain links in the middle.
4. Attach the chains to the eye bolts.

Adjustment Instructions:
1: If the table tilts to one side or the other, you can tighten the chains on the high side.

1: For tiny adjustments, remove the chain from an eye bolt, rotate the eye bolt some, and re-attach.
2: For moderate adjustments, you can rotate the eye bolt without removing the chain, and the twist in the chain will add tension.
3: For large adjustments, you can disconnect the chain, twist the chain in your hand, and then re-attach in the twisted state.

2: If the table wants to twist, then quarter-turn one of the center eye bolts.
