Tactile Chemistry learning atoms

pinshape

Thinking about the chemistry classes I took when I was a student, I realized that colors were always used on models to represent molecules. For people without sight, that's a major problem. From there, I developed this series of textured spheres, allowing the blind to feel the reliefs and quickly identify the type of atom being used. This way, they can form the molecule to be studied and feel its shape. I can picture this being printed in schools for the blind, helping chemistry teachers complete their lessons. Here's a short demonstration video showing this model in action: https://vimeo.com/216056369 Print Instructions: This design was made for FDM printing, but it will look even better when printed with SLA technology. Depending on your printer's tolerance, you may need to scale down the connectors to 99% so they fit perfectly. In my case, I used the regular scale and cleaned up the ends a little bit after printing each piece. I've prepared a file with all the atoms and also split each atom into a separate file, making it easy to multiply them as needed. You can also print each atom in a different color for better organization when storing them. Recommended settings: 2 vertical perimeter shells 3 top and bottom solid layers 0.2mm layer height 10% infill I hope you like this design and find it very useful!
