Fittle is the world's first 3D-printed Braille puzzle.
A new way for the blind and visually impaired to learn and discover. Because Fittle models are available open source to be simply 3D-printed at almost zero cost, learning Braille becomes more accessible than ever.
To further complete the Braille literacy puzzle, the Fittle Project is raising funds to provide 3D printers to communities in developing countries who couldn’t afford expensive learning devices before.
