Tensegrity Table.

The top pieces floats and holds weight, while only being connected with string! Magic! Science!

I used trucker hitch knots to attach the top and bottom together: https://www.animatedknots.com/truckers-hitch-knot

Both pieces are the same,  you can print the .STL file twice, or the 3MF file has both pieces together for easy printing. Have fun!

Update: Thanks to some helpful comments, I realized that I failed to upload the second half of this model. I had incorrectly assumed that when I had made it that both the top and bottom were the same--this is not the case. The second half is uploaded now!
