  • Printing. How might someone find and select appropriate models for printing? What are effective workarounds for working with accessible 3D printing hardware and design software? E.g., how might I teach or learn how to use OpenScad with blind students? 
  • Practice. How might teachers, blind students, or blind individuals access 3D printing?
