Bring 3D Printing and Making into Your Classroom. Join NapaLearns and the Napa County Office of Education to learn more about how to meaningfully integrate making into your projects. Tinkercad is a free 3D Design tool that allows students to easily create complex, 3D models. Join AutoDesk and experienced guest presenters who will show you how to design and print in 3D! FAQs What should I bring to the workshop? Bring your laptop or Chromebook. If you don't have a device one will be provided for you. Bring a colleague, it's always fun to learn with a buddy! Bring your questions, ideas, and inspiration to share with our group. We are excited to have you participating.
