FIRST Earrings

thingiverse

Every year at the World Robotics Competition in St. Louis MO, attendees are wowed by these fantastic earrings. As we've yet to attend Worlds, our CAD designer created models for 3D printing. Though compact in size, these earrings require considerable time and separate print jobs for red triangles, white circles, and blue squares. Replace the circle with a cool gear! Don't forget to change filaments between colors; allow 30 seconds for thorough extrusion cleanup. The circle's slot simplifies assembly of the parts.
