# MacroPad Braille Keycaps ## Overview https://youtu.be/xQzjwiSfizI Accessibility Keycaps for the Mechanical Keyboards. These keycaps are 3D printed with the braille alphabet so folks can touch and feel their keyboard shortcuts. We thought it’d be nice to have audible feedback so a tone is played when a key is pressed. The Adafruit MacroPad features the RP2040 chip and has a built-in speaker for generating tones and playing audio files. We think the Adafruit MacroPad is great for making custom input devices for accessibility projects. ![3d_printing_on-stand.jpg](https://cdn-learn.adafruit.com/assets/assets/000/103/519/medium640/3d_printing_on-stand.jpg?1626811842) ![3d_printing_bumps-close.jpg](https://cdn-learn.adafruit.com/assets/assets/000/103/520/medium640/3d_printing_bumps-close.jpg?1626812030) Braille is a writing system that features raised bumps called cells. To make these keycaps, we referenced a peel-and-stick overlay that features functions keys and special characters. The keycaps are compatible with Cherry MX and Kailh Box switches. You can print the keycaps in one piece or just the top cover for existing keycaps. The keycaps are installed by press fitting them over the stem of the mechanical key switch. The resolution and print quality is good enough for making this style of keycaps. ![3d_printing_add-ons.jpg](https://cdn-learn.adafruit.com/assets/assets/000/103/502/medium640/3d_printing_add-ons.jpg?1626720029) ![3d_printing_braille-sheet.jpg](https://cdn-learn.adafruit.com/assets/assets/000/103/514/medium640/3d_printing_braille-sheet.jpg?1626799536) ## Parts ### Adafruit MACROPAD RP2040 Bare Bones - 3x4 Keys + Encoder + OLED [Adafruit MACROPAD RP2040 Bare Bones - 3x4 Keys + Encoder + OLED](https://www.adafruit.com/product/5100) Strap yourself in, we're launching in T-minus 10 seconds...Destination?
