Introduction: Computer Keyboard With 3D Printed Braille Keys
Globally the number of people of all ages visually impaired is estimated to be 285 million, of whom 39 million are blind.
Impact of vision impairment.
Young children with early onset severe vision impairment can experience delayed motor, language, emotional, social and cognitive development, with lifelong consequences. School-age children with vision impairment can also experience lower levels of educational achievement.
Vision impairment severely impacts quality of life among adult populations. Adults with vision impairment often have lower rates of employability. In the case of older adults, vision impairment can contribute to social isolation, difficulty walking, a higher risk of falls and fractures, and a greater likelihood of early entry into nursing or care homes.
Unless people have interacted with someone who has visual impairment or blindness they have to be educated about people who is different to make life more accessible with more opportunities for all and have meaningful contribution.
I have been searching for computer keyboard with braille characters but couldn't find any good quality board with fair price. Therefore in this instructable I will show you how to create braille board from a regular keyboard.
3D printed braille keys
Step 1: Print the Keys
Find the model of 3D printable braille keyboard stickers (I downloaded design from https://pinshape.com/items/33753-3d-printed-braille-keyboard-stickers) and order the print from local 3D printing service (I choose https://imprimakers.com/en/)
The printed keyboard stickers from the example above was getting over the edge of the keys, I would prefer a reduced key size for my keyboard. If these tiles do not fit the keys on your keyboard, try scaling it down by a few millimeters.
Material: PLA (lactic polyacid). It is the most used in 3D printing with FDM technology. Size (16.05 × 32 × 0.29 cm).
Step 2: Stick the Keys to the Board
These key covers are designed to be glued or taped to the keys on a keyboard. I took the plastic glue which dries out quickly.
The most time takes finding the characters for each pattern.
