NORTH SALEM, N.Y.— North Salem High School senior Richard O’Leary utilized the school library’s 3-D printer as a part of his Eagle Scout Project for the North Salem Open Land Foundation’s Gaymark Preserve.

Part of his project involved leveraging the technology of QR codes to help hikers learn about bluebirds in the Northeast. His innovative idea to 3-D printing the code as a plate allowed for a sturdy, weatherproof and aesthetically pleasing object to hang in the open land. Creative and critical thinking are essential tools in problem solving.
