It provides a way to produce basic fasteners locally when a commercial hardware source is unavailable, using customizable print files rather than a single fixed part.\n\nThe fasteners are 3D printed using ABS plastic filament, with a total production time of approximately 150 minutes.\n\n{| class=\"wikitable\"\n! colspan=\"2\" |More Product Information\n|-\n| Author Code\n| GN020\n|-\n| Documentation License\n| CC-BY-4.0\n|-\n| Open Hardware License\n| CERN\n|-\n| OSHWA Certification\n| December 15, 2019\n|-\n| OSHWA UID\n| US000193\n|-\n| Start Date (Development)\n| December 1, 2013\n|-\n| End Date (Development)\n| April 1, 2019\n|-\n| Designer\n| Mike Mattala\n|-\n| Maker\n| Brynmor John\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 = Spare Parts\n| sdg = SDG09 Industry innovation and infrastructure\n| authors = Charles Vincent Barrete\n| organizations = Field Ready\n| license = CC-BY-SA-4.0\n}}"}
