A smallish tensegrity stand (the wood top in the picture is 100 mm x 7 mm) I made to put my origami and other little things on.
The holes for the wire are meant for fish wire but it should possible to use a thin rope (1 mm) too.
Printing Suggestions
The top and bottom parts need minimal supports at the center, I obtained a good results using the organic type, anywhere else are not needed. With 10% infill and 2 perimeters wall the printed parts feels sturdy enough for me. I added more infill near the cable “hooks”: see the 3mf files (note that I use a 0.3 mm nozzle, so it's not ready to use if you have a 0.4 mm).
Assembly Suggestions
I started with the three external wires: once in place they need to be as close as possible to the same length. I had some trouble at first inserting the wires in the bottom part but I found a trick consisting in bending the wire for a few mm. Once a wire is in I secured it with a simple knot trying trying to make it the same length as the previous one.
At last I placed the central wire trying to make it as tense as possible.
I'm not completely happy with the assembly process because it took me quite a bit of time and I would like it be easier but it's also the first time I try to assemble a model like this. Maybe I just need a bit more practice :p. Anyway I think the end result is nice so I decided to share.
The author marked this model as their own original creation.
