Teaching science, technology, engineering, and mathematics (STEM) subjects to blind and low vision (BLV) students is a major challenge. Emerging technologies like three-dimensional (3D) printing enable us to provide tools and techniques which can help us create working modular molecular and chemical models for tactile perception. In this self-initiative project, we have designed and developed 3D printed scalable Braille models. The model contains Braille labels along with alphanumerical impressions to be used readily by both the BLV students as well as their teachers. We are also freely sharing the open-source repository of basic building block models design files for writing chemical formulas, equations, and ionic states.
