[BlindMath] Accessible 3D printing

[Haden Pike]

This topic comes up every so often, but I can't recall what, if 
anything, was suggested. Nor can I find a resource for accessible 3D 
printing, thus this message. Does such a resource exist? If not, and 
assuming accessible 3D printing is both possible and the necessary 
materials are available, I intend to create this resource. I am not 
asking for a repository of existing models to download and print, but 
rather how to create these models myself,.
