Braille cell - letter learning kit

pinshape

Braille is a tactile writing system used by people who are blind or visually impaired. It's written on rectangular blocks called cells, each cell containing six spaces organized in two columns where raised dots can be placed. This project is a learning kit designed for use in a classroom but isn't limited to it. The frame consists of six square individual cells that rotate on center pins. Each square contains a dot on one of its faces, making it easy to form Braille letters. Every frame has two raised dots on the top and two small dents below to help learners know which side is front and to make stacking easier. Settings The entire project was printed with PLA at recommended settings: 220°C, 0.2 layer height, 15% infill, and three solid top and bottom layers. Assembly Every STL filename contains the required quantity for each part. With all pieces ready, start by placing two "pino_x2.stl" in holes on "estrutura_x1.stl." As soon as they exit the holes, place one "espacador_x8.stl" on each followed by two "ponto_cubo_x6.stl." Repeat this pattern until all square cells are correctly placed on the two center pins. Slightly bend the pins and place the last two "espacador_x8.stl," then align the pins with the frame's holes and push them in. Using a few drops of super glue, attach the "ponto_botao_x6.stl" to the top of squares, and add a drop of glue to the base where the pins were inserted to prevent them from coming loose. Alternatively, you can print a square with a dot already placed by using "ponto_v2_x6.stl" and ignoring "ponto_botao_x6.stl" and "ponto_cubo_x6.stl."
