This 18650 battery assembly jig is a professionally designed CAD model engineered to securely hold 10 standard 18650 lithium-ion cells in precise alignment during battery pack assembly. The jig maintains consistent spacing and positioning, making it ideal for layout, spot-welding preparation, and repeatable pack construction.

Designed for makers, engineers, and battery pack builders, this fixture reduces setup time and assembly errors while improving overall build quality. The robust, clean geometry is suitable for 3D printing or machining and can be easily modified to support alternative pack configurations or tolerances.

Perfect for prototyping, small-batch production, and educational projects, this model is delivered as a high-quality CAD file ready for manufacturing or integration into an existing battery-building workflow.
