If you are making one of these, consider sending a tip - every dollar helps to create more things like this and encourage more open sourcing of designs. This is a 3d printable bracket designed to allow you to use Ridgid brand 18V lithium batteries from their cordless power tool series as portable power for projects. Ridgid brand batteries with internal battery management, short circuit protection, overdischarge protection, rugged case, and electronic fuel gauge provide a safer means of lithium power for projects where weight constraints aren't as critical as safety.

Custom Section Electrical Cautions 18V battery has nominal 20.5VDC falling to 18VDC when discharged. Provide appropriate gauge wires when connecting to the battery as high current output is available from the battery, and normal battery output can exceed current capability of wiring or circuitry. For safety add some means of fault current protection (fuse, PTC fuse/polyfuse, breaker). No responsibility is assumed for this device, build and use at your own risk.
