Probably the best person to contact would be Nic Bonne who runs the Tactile Universe https://tactileuniverse.org/ Nic is a visually impaired professional astronomer who has made a series of 3D printed tactile objects of planets, moons, galaxies etc. Last year at the NLO we ran a one day Tactile Astronomy Day for our local charity Moor Vision https://www.moorvision.org/ We were able to offer NASA braille constellation charts, lunar craters made out of plaster of paris, planets on a string to show scale of solar system and letting students feel a telescope, lens and eyepiece. It was as a rewarding experience for those helping as it was for the visually impaired.
