Steel cable: Not legal on the Minbot. You can use non-metallic rope or cord.

Henry, check the Q&A I linked to again.

Polycarbonate can be cold bent, and in most cases it will not break. It can be bent in an apron break or a press break. If you are going to bend it over onto itself you will need to stress release the material with heat. Many hobbyists do it with a heat gun.

If you are looking for a spring tension, you could stack layers of different thickness to create a leaf spring. This will allow you to play with different tensions. It is very unlikely that you will break Polycarbonate using it this way.
