[Whoawhatsis] realized that he could slightly change his OpenSCAD Braille model to fulfill a teacher's request for tiles that each have a lower-case letter plus the Braille equivalent of that letter, to use to teach students Braille. So, he went ahead and created a set, using the principles we have discovered thus far. (For instance, printing Braille on vertical faces.)
They've been downloaded 21 times in 2 days. They even fit very tidily in one of those 0.14 liter "Really Useful Boxes" from Staples. The tiles are small, and so most appropriate for a school environment away from anyone who might want to try and eat them.
There are a lot of requests on the Google Group - if you know how to
do 3D modeling, how about a New Year's resolution to create a model a
teacher needs for a blind student? Jump on over to the group, pick an
open request, and go for it. Instructions in the Instructions section
here, or linked on the Google Group. Happy New Year!
