So I guess it was just a day or two ago I remade MrKindergarten's Word cube. In the comments section Gillian703 asked if there was a way to add braille as one of the fonts in the Customizer? I didn't know how to do that, but I was able to instead able to just make a braille font for it. So now here is the cube in braille. (full instructions about the purpose and intent of the word cube still to be found under MrKindergarten's original version.
If anyone can provide feedback on how to help improve this or make it more useful I'd be glad to hear it and improve it in any way. (Currently it only does lower case letters, because I do not know the ideal/standard way to place the dot 6 to denote it is a capital letter)
cleaned up the code some in the morning and set default rotation to a more printable way.
Also added a bump at the start of the cube so they can feel where to start reading.
I'd advise printing this standing up tall ways (I guess is how you'd put it) So the braille can be printed. Then just clean it up a bit so the middle cube can spin.
Overview and Background
I'm not a teacher, I helped teach a 3d modeling class in my high school during summer school after I graduated. Point of this is to help make more teaching aids available to those who need it. I guess also to help those who are visually impaired or just interested in learning braille have another way to do so from an early age.
Lesson Plan and Activity
Option 1: Lower Level
Give the cubes to the children and have them just enjoy reading the words out loud.
Let them play with the cubes and make it a puzzle where they have to 'find' all 4 real words on the cube.
As far as I am concerned all you need is a captive audience and well, the cubes.
Warning, this will probably take a while (it took about an hour on this site, so I'd advise just downloading the scad script and rendering it yourself if you're in a rush) to render/make due to the large number of circles. If it seems like it is a major issue, I'll swap them out with cylinders instead.
Also when entering in words, only lowercase letters work.
