The use of physical 3D models in astronomy communication with the public has already been proven as an effective way to disseminate science, with the benefit of including the blind and visually impaired community. We present here a set of ten new models (such as Laniakea and Ho’oleilana) based on real data and created using an organic 3D design, which has made them more accurate while also making them attractive and inspiring. We tested the models with non-specialist audiences and with persons who are blind, who helped improve the final designs and highlighted their usefulness in astronomy communication. The models are available on the A Touch of the Universe website, and a collection of four educational activities has also been developed and submitted for publication in the AstroEDU repository following a peer-review process. This project demonstrates how 3D printing can foster inclusion and multisensory engagement in astronomy education and outreach.
