BOM: Printed with ROSA3D High Speed PLA Signal Violet
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.
