It is intended as a fabrication aid for disaster response and field settings, where standard drafting tools may not be readily available.\n\nThe set square is 3D printed using ABS plastic filament, providing a durable, dimensionally accurate straightedge that can be fabricated locally when a physical set square cannot be sourced nearby.\n\n[[File:GN017 Image CAD.jpg|thumb|CAD image of the Set Square]]\n\n{{Device data|design-files=https://www.appropedia.org/File:GN017_Eng_Dwg.zip|schematics=https://www.appropedia.org/File:GN017_CAD.zip}}\n\n[[File:GN017 Image Use.jpg|thumb|Set Square being used]]\n\n{| class=\"wikitable\"\n! colspan=\"2\" |More Product Information\n|-\n| Author Code\n| GN017\n|-\n| Documentation License\n| CC-BY-4.0\n|-\n| Open Hardware License\n| CERN\n|-\n| Start Date (Development)\n| February 23, 2018\n|-\n| End Date (Development)\n| February 23, 2018\n|-\n| Designer\n| Tom van der Vaart\n|-\n| Maker\n| Tom van der Vaart\n|-\n| Main Materials\n| ABS Plastic\n|}\n\n== Readiness Levels ==\n\n''Levels are identified based on this reference:'' [[Field Ready Readiness Levels]]\n\n{| class=\"wikitable\"\n!

A maker manual provides step-by-step instructions for replicating the design, including materials, tools, and assembly guidance, so that makers in different locations can build the product accurately and consistently. A user manual, where applicable, explains how to properly set up, use, and maintain the product once it is built, helping ensure it performs safely and as intended for the end user. Together, these manuals make the design accessible to both fabricators and the people who ultimately rely on the product.\n}}{{Page data\n| part-of = Global Field Ready Portfolio\n| keywords = Measuring tool\n| sdg = SDG09 Industry innovation and infrastructure\n| authors = Charles Vincent Barrete\n| organizations = Field Ready\n| license = CC-BY-SA-4.0\n}}"}
