A revised version of polymaker's openscad code. See http://kitwallace.posterous.com/printing-braille-label-via-openscad for discussion. The main improvement is autosizing the width of the label.
I had trouble printing from this on a Makerbot - dots were indistinct and joined by many threads. It has been suggested that some software could produce G-code which created mulitple layers of a single dot rather than a single layer for every dot. I have yet to try this approach.
