Read here about how cardboard material can be helpful when constructing tensegrity structures.

Cardboard Tubes as struts[edit]

Cardboard tubes may be used as struts for building a tensegrity.

For example, Kvncsy of Istanbul, Turkey createded a 3 strut platform for his cats.

Cardboard Scaffolds Help Create Tensegrity Structures[edit]

How to construct a tensegrity by using a cardboard scaffold

Construct a cardboard model of the target regular polyhedra. In Connelly's article, he shows a cube constructed of six stiff carboard sides.

Near the vertices, cut holes large enough to insert the compression members, but tight enough to hold the struts snugly. Locations need not be precisely correct.
Insert the notched struts through the holes.
Thread rubber bands through the notches.
Replace rubber bands with string, nylon thread or dacron for longevity.

Phil Earnhardt also proposed a similar cardboard scaffold for constructing a six strut tensegrity.

Anthony Pugh in his introduction to tensegrity also advises that a cardboard scaffold can be helpful. See p.49.
