+/**
+ * Creates one instance of a bottle clip name tag. The default values are
+ * suitable for 0.5l Club Mate bottles (and similar bottles). By default, logo
+ * and text are placed on the name tag so they both share half the height. If
+ * there is no logo, the text uses the total height instead.
+ * Parameters:
+ * ru: the radius on the upper side of the clip
+ * rl: the radius on the lower side of the clip
+ * ht: the height of the clip
+ * width: the thickness of the wall. Values near 2.5 usually result in a good
+ *	clippiness for PLA prints.
+ * name: the name that is printed on your name tag. For the default ru/rt/ht
+ *	values, this string should not exceed 18 characters to fit on the name tag.
+ * gap: width of the opening gap, in degrees. For rigid materials this value
+ *  usually needs to be near 180 (but if you set it to >= 180, you won't have
+ *  anything left for holding the clip on the bottle). For flexible materials
+ *  like Ninjaflex, choose something near 0. For springy materials like PLA or
+ *  ABS, 90 has proven to be a good value.
+ * logo: the path to a DXF file representing a logo that should be put above
+ *	the name. Logo files should be no larger than 50 units in height and should
+ *	be centered on the point (25,25). Also all units in the DXF file should be
+ *	in mm. This parameter can be empty; in this case, the text uses the total
+ *	height of the name tag.
+ * font: the path to a font for Write.scad.
