Braille font module EXPANDED - Nemeth

Description

This is a remix and expansion of the fantastic OpenSCAD braille module posted by Sean Tikkun and drayde. The additional characters allow for complete braille transcription. Here's the text from jaqtikkun’s original posting: "DO NOT SCALE! Any scaling could render the braille unreadable. This is a modification of the module posted with added elements for part word and lower cell contractions, numbers, and some basic composition signs. It will enable the production of accurate name tags in braille that are appropriately contracted. I will continue to update this module so please let me know if you find discrepancies. Thanks drayde for the great work. The spatial orientation of the code helped a lot! With this tool I can now label 3D manipulatives for blind students!" ***GETTING STARTED*** Create braille labels by editing the "chars" text at the end of the text editor. The default text is a math expression written in the Nemeth braille math code: 3×4 = 12. For plain text, you may prefer to begin with this text: chars = ["A", "B", "C", "space", "D", "E", "F", "space", "G", "H", "I"]; char_count = 11; Once you've entered your text, you'll need to preview, render, and export the model as an .stl for printing or adding to other models. For smooth braille, avoid printing braille laying flat with the dots facing up. ***MAKE YOUR OWN CHARACTERS*** Copy and paste this text into the list of characters: } else if (char == "M") { letter([ 1,1, 0,0, 1,0 ]); The ones and zeros are in the shape of a braille cell. A one adds a dot, and a zero has no dot. ***UPDATES*** These “dot#” characters are the only characters not included in the original module. They allow for complete transcription of any text into braille. "dot4" "dot5" "dot45" "dot456" "dot46" "dot56" *originally included as “let” Nemeth Numbers – These characters were all included as a contraction or punctuation in the original module. For ease of use when creating Nemeth text, redundant characters were added for Nemeth numbers and symbols. Symbol “n.” is a Nemeth decimal. "n1" "n2" "n3" "n4" "n5 "n6" "n7" "n8" "n9" "n0" "+" "n."
