Cable chain (work in progress)

This cable chain is a design study for a major other project. The goal was
- to design a cable chain that auomatically follows some design parameters
- to have an adjustable angular range in the hinges
- to achieve printability without supports and
- to check the functionality.

Those who are familiar with OpenScad may change the following design parameters:
- width and height of the inner space for the cables
- length of the elements
- angular range in the hinges
