The Battery Terminal Wire Clamp is a 3D printed clamp designed to safely secure wires to car battery terminals. It provides a more secure and controlled connection point than improvised wiring methods, reducing the risk of loose connections, accidental disconnection, or short circuits when working with battery power in the field.
The clamp is 3D printed using ABS plastic filament, chosen for its strength and durability in a component that must maintain a secure mechanical grip under regular use.

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.
