Here's how a tensegrity passionfruit climber can be re-purposed from a thrown out clothes airer.

Step 1: Cut Some Corners Off a Thrown Out Clothes Airer

Having come across a thrown out Clothes Airier it gave me the idea that it could be re-purposed to make a tensegrity tower, suitable for a passionfruit plant to grow up.

The Corners were cut from the clothes airier using a small pipe cutter.
These corner where bent inwards to about 60 degrees, some of the corners squished in a bit and while this could probably be have prevented by filling the tubes first with sand, I wasn't too concerned about it.

Step 2: Equal Each Side

Cut each side of a corner to be the same length.

If some of corners a longer than other arrange them from the longest to shortest.

Step 3: The 'Persuader'

Wooden plugs for the ends can be made from suitable diameter dowel.
They are tapered with a rasp and then inserted into the ends with the use of a 'persuader' (otherwise known as a hammer).

Step 4: Eye Hook

A hole is drilled into the end and a eye hook screwed in.

Step 5: Joining Two

Two are joined with a bolt and nut as shown in the photo.

Step 6: Making a Base

A base can be made from a couple of timber 4 by 2's as shown in the photos. (In some countries it's called 2 by 4's and referred to as lumber)

Step 7: Connecting the Base

Here's how they are connected together. You might like to add some glue and screw them together.

Step 8: Fixing the Stand

The bottom unit was fixed to be base by drilling a couple of holes, inserting some dowel and striking them with the persuader.

Step 9: Attaching the Uprights

The units are suspended above the base unit using cord. You will able to work out how to supend then one above the other with a bit of trial and error. The method which worked well for me was to have a cord come up and then across (see highlighted in a photo above). With two main cords running from bottom to top, giving vertical support.

Step 10: Cord 'knots'

No knots were tied in this project. Instead a bolt, washer and nut system is used to secure the cords between the compression members.

Step 11: Treating the Ends

Heat the cut ends of the cords with a lighter and then clamped with a pair of pillars to stop them fraying. Don't use your fingers as the melted ends will be hot. Hint: do this after you have finished tightening the stand.
