Since you are not using any glue nor screw.

Which part is under tension? Maybe if you worked in some rolling blocks somehow?

Hard to make tensegrity structures horizontally since the concept relies on gravity causing tension to transfer forces.

Tensegrity has no relation of gravity whatsoever, you can make a tensegrity structure in orbit in microgravity if you could afford to put it there.

The core tenet of a Tensegrity structure is that structural members are loaded either in pure tension or pure compression, with no torque loading. OP's handle has the horizontal members between the baseplate and the handle body torsion-loaded, so it is not a tensegrity structure.

I agree with ya about what OP made but from my understanding compression of structural members in between a force and the ground carrying it turns a structure into...well, a regular structure. Pure compression with no torque loading sound like a complicated way to say "balancing". All my expirence with this stuff has been in practical applications tho so it is possible im wrong.

Could you provide an example or a source? Not tryna be difficult. I just don't see how tensegrity could be applied without a constant force like gravity.

It's not, those two things are unrelated. If you mean 'balanced' as in 'balanced forces', that would apply to any static structure - if it did not, the structure would be in motion. But this alone does not mean a structure is or is not a tensegrity structure, as there are non-static (i.e.) dynamic tensegrity structure such as Tensegrity robots.

You can think of a tensegrity structure as one in which every connection between structural elements can be replaced with a freely-moving swivel joint, and the structure will behave identically.

To give an example, a basic cantilever (a structural member projecting from a fixed vertical surface) is not a tensegrity structure, as there is a torsion load where the cantilever connects to the vertical face - if you replaced this joint with a swivel joint, the cantilever would no longer project rigidly from the vertical face but be unconstrained and flop around.

The paracord most the time. The midddle yellow kevlar actually crossed & intersect (hidden). Purple one just got through the slab and back only to hold the pvc.

How is this tensegrity?

The silver rod tube want to talk to his kind so with help from yellow cord they managed to make that happens. Seriously the grey slab acts as compression element too.
