The Owl headphone wrapper customizable in customizer for those with no openscad, and some extra options: scaling of size and scaling of height

I like the Owl headphone wrapper, but would like to use it also for usb cables, ... . The size of the original is for some cords too large then , so I added some scaling options to be able to print this in the size I want without weakening the result.

Note: Set plug hole to 0 to have no plug hole.
