All, I've attached 3 files which should make it easier to test my braille code. First is the generic braille code, braille.scad. This library takes a unicode braille string and generates 3D braille chars. Second is a rough transcription program. It takes a US English string and converts it to unicode braille characters (which can then be passed to the generic braille library). Third is a test program written in OpenSCAD. If you pass it a text string, it should generate a braille sign/label. $ openscad test1.scad -D 'text="Hello, world!"' -o "Hello.stl" PS: Um, I am embarrassed to say that I posted the wrong code a moment ago for the braille transcription.  Please us the code in the attached file instead.
