blind basic maths

pinshape

I believe that learning math is truly vital because you need it throughout your entire life, so I designed this board where you can place five pieces with a number on them to perform basic math operations. The interesting aspect of it, apart from being simple, quick, and easy to print, is that all the pieces have the number and its Braille translation, making it possible for both blind and sighted kids to learn numbers and math easily. I really hope you'll like my design; it was very straightforward to create, but I think it can be incredibly useful. I learned a lot while making it, thanks for reading, and good luck to all the participants! Unfortunately, I wasn't able to print the board due to adhesion issues (I'm still new to 3D printing), so I've included all the files I did manage to print: one, two, plus, minus, and the board. Sorry if I made any grammar mistakes; English isn't my native language.
