Yes it is. All we know rubic cube is made for people who can see every colour. All cubic things has six face. So on rubic cube faces painted with different colours like red, blue, yellow and others. But blind people can’t see colour or anything other. They can only read with Braille Alphabet which invented by Louis Braille in 1821. It has up to six relief spots. By this way blind people read with their fingers. So I decided to creade a face tile rubic cube with Braille Alphabet. It has six different face tile with colours first letter in Braille Alphabet. You can 3d print them easly and glue on the rubice cube by the name of colour. You can reach this projects 3d files from link below:
