Parametric cable holder

This is a parametric cable holder I made in scad. This is the first thing I made in scad but I think it turned out well.
The width is the thickness of the desk, the height and length are the height and length of the cable holder (it mainly affects the clip part), the thickness is added to the width, height, and length for the outer width, length, and height. The cable angle is the angle of the whole top part, and the cable diameter should be obvious.
