Braille Trainer 3 (Braille On Rail)

Here are the parts for Braille Trainer v3 - a continuation of the Braille Trainer project.
Created with SolidWorks 2017.
Code for Braille Trainer v3: github.com/braille-systems/braille-display.
The primary new feature: a multi-character refreshable Braille display (previous designes comprised a single Braille cell).
This mechanical display was conceived as a low-cost alternative for existing piezoelectric Braille displays. The model is currently under development, but if you are interested in this design and would like to access parts in a format other than SolidWorks documents, feel free to email me at [email protected]
