Kids try 3D printing with both 3D pens and printers, design objects in the free CAD program Tinkercad, and turn pieces of fruit into game controllers and keyboards with Makey Makey circuit boards, among other stations. Having high-school students as guides makes the tech approachable for elementary and middle-school kids who have never used CAD or a 3D printer. The session lasts about 90 minutes in the museum in downtown Gilbert and is free, but registration is required and closes at noon on the Friday before. ## Similar picks in Phoenix - [Girls in STEM: Astro Adventures](https://grassyknees.com/phoenix/activities/girls-in-stem-astro-adventures--listing-9759f753ee42fd6eb9c294bd) — Sat, Nov 14 · 9:00 AM · CREATE at Arizona Science Center — confirm classroom · checked Oct 12.
