Hey folks, this week we’re making accessibility buttons for the Adafruit PyGamer. These buttons are 3d printed with the braille alphabet so folks can touch and feel the buttons.

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

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

To remove the parts from the bed, I like to use a razor blade. Just need to carefully get the edge of the blade underneath the part without scratching the bed.

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

Just a small drop of superglue is all it needs to bond to the caps. Once you get them on you can test out the button presses and get a feel for the dots. I think it’s interesting how your well fingertips can sense such fine details like these little dots.

UPDATE August 6 2019

Version 2 is 2mm thinner and includes an updated bottom half with cutouts for female headers.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
