4Bros Battery Box

4Bros 3D-Printed Battery Box

The 4Bros Battery Box offers a simple, affordable way to organize and store common emergency, firearm, and optic batteries. Designed for light-duty use, it’s ideal for a go bag, vehicle, workbench, or household drawer.

Battery Capacity & Organization

The internal tray and lid are purpose-built to securely hold a wide range of commonly used batteries:

• Up to 11 AAA batteries
• Up to 14 AA batteries
• Up to 22 CR123 batteries
• Lid storage for 3 × 18650 batteries
• Lid storage for 4 × 1632 batteries
• Lid storage for 4 × 2032 batteries

Material & Construction

This battery box is 3D printed and assembled in-house using PETG, a polymer known for its durability and elasticity. All components are printed except for the latch and lid pins, which are added for reliable closure and long-term use.

Use Case & Limitations

This is a light-duty storage solution designed for organization—not a molded, duty-rated product. Due to the nature of 3D printing, minor cosmetic variations may be present and are considered normal.
