My students had a dance performance with the theme "Night at the Movies." I decided to choose a story based on "The Diamond" episode from the old Mission: Impossible television show. To make it fun for the kids and convey the story better to the audience, I decided to build an interactive 3D printed diamond. In this tutorial, you will learn how to 3D print a model and embed electronics in a theatrical prop.
