Libro is a RepRap 3D printer designed to be created at public library makerspaces. Design emphasis is placed on 'foolproof' ease of assembly, minimal tool use, and short overall component print time. This development was originally begun as a makerspace program for the Pueblo City-County Library District by David Hartkop, PCCLD Technology Trainer.
