Wrench

The Wrench is a parametric, 3D printable wrench design that allows users to generate a wrench sized to their specific requirements, rather than being limited to a single fixed size. It is intended as a fabrication option when a commercially sized wrench is unavailable.

The wrench is 3D printed using ABS plastic filament, with a total production time of approximately 10 minutes.

1. Download the SLDPRT file from the CAD files to customize the wrench size.
2. Open the .SCAD file using OpenSCAD software to set the preferred wrench size and generate an STL file. Note: the installation location path must be added to use the "shapes.scad" library. Alternatively, download the STL file directly from the CAD files to 3D print the current default size.
3. Open the STL file using slicing software and prepare for 3D printing, using the settings below.

About the manuals

Field Ready develops manuals to support both the fabrication and safe use of its products. 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.
