/**
|
|
* Creates one instance of a bottle clip name tag.
|
|
* 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.
|
|
* 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.
|
|
* font: the path to a font for Write.scad.
