I don't know specifically how helpful this is for everyone, but in playing around with learning Openscad, I first developed a program that created bound books for printing in 3D printers, then I said to myself "isn't this perfect for Braille?" I started the project today and I mostly completed it. If you happen to have a dual-extruded 3D printer with Ninjaflex and AVS filament, and a little GitHub knowledge, you can now print entire books in Braille from home simply by supplying the raw text and clicking run! Hope you like it (it is in Alpha so be patient on new updates!)
