Need to build a wider, high-capacity lithium-ion pack? This triple-row set of 18650 cell spacers provides the structural stability and precise spacing required for professional-grade DIY batteries.

Key Features:

• Spot Welding Ready: Built-in alignment guides and indentations for nickel strips. These keep the strips perfectly centered over the battery terminals during spot welding, preventing shorts and ensuring strong welds.
• Integrated Wire Routing: Designed with channels/holes to neatly run balance wires or main power leads without adding external bulk to your pack.
• Triple Row Configurations: Includes 6 different sizes to build larger pack geometries: 3x2, 3x3, 3x4, 3x5, 3x6, and 3x7.
• Thermal Management: Proper spacing between cells ensures adequate airflow, preventing dangerous heat buildup during charge/discharge cycles.

Printing Instructions:

• Orientation: Print flat on the bed.
• Supports: NONE. The wire routing channels and cell cutouts are designed to bridge cleanly without supports.
• Material: PETG, ABS, or ASA are strongly recommended due to their temperature resistance. Avoid PLA for battery packs, as it can soften and warp from cell heat.
• Infill: 20-30% (Grid/Gyroid) with at least 3 walls for solid structural integrity.
