I printed this project for a blind girl in our church: Braille learning, training, translate machine by Whiletrue

I wanted to have a place to store the tiles and also wanted to have room for more than one set of the alphabet. I printed quite a few of the most used letters along with two of the frames. I needed to add rubber bands to hold the letters in the frames since we close up the box each week with messages for one another.

Both the top and bottom of the box are deep enough to hold quite a few letters along with the frames. 

The box prints in one piece and the hinges work well.
