Braille Alphabet

You can make additional accessories for the Adafruit PyGamer like these for accessibility. These buttons are 3d printed with the Braille alphabet so folks can touch and feel the buttons.

3D Printed Braille Buttons

We made a full set of these button caps to press fit over the PyGamer switches. They’re printed flat side down with the stem facing up. All 26 buttons fit on the bed of the 3D printer and only took a half hour.

Slicing Sets

They’re printed flat side down with the stem facing up. All button covers fit on the bed of the 3D printer and only took a half hour to print a whole set. The button caps can be printed in a separate set. These were laid out with a bit of spacing between each cap.

Button Covers

The braille alphabet will be printed on little cover pieces and super glued on top. Each cover piece has it’s own set of dots so you can pick and place any letter you like. 

Installing Covers

While picking out the covers, it might be a bit tricky to make out the alphabet, so I suggest a cheat sheet. You’ll also need to be cautious of the orientation when placing the covers.

Just a small drop of superglue is all each key needs to bond to the caps (so be sure of your choice and orientation). Once you get them on, you can test out the button presses and get a feel for the dots.

Customize

The alphabet consists of dots in a 2 by 3 configuration. These dots are quite small, but we were able to fit them on buttons with a diameter of 9mm. I think it’s interesting how your well fingertips can sense such fine details like these little dots.
