parametric cable comb v2

Updated version that supports flat cables.

I wanted a way to quickly create and print cable-runners for gathering the various cables around my computer and the rest of the house. While there are plenty of parametric cablerunners available, none (as far as I can tell) allow one to use different cable diameters of an arbitrary amount.

The scad-file uses recursion to do its thing.
The design is extremely basic with overlapping hollow cylinders.

Top of the scad has 3 parameters

| Parameter | Sample | Description |
| --------- | -------- | ------|
| cableDiameters | [6.25,[3.4,6.7],[2.7,5.5]] | Takes an array of arrays or numbers. If number, creates a circular holder. If list, expects a width+length of the cable. |
| wallThickness | 2 | Wall thickness |
| length | 10 | Length along the cables. |
