BOM: Printed with ROSA3D High Speed PLA Signal Violet
Building a massive, high-capacity power bank or a custom e-bike battery? This quad-row (4x) set of 18650 cell spacers provides the ultimate structural stability for large DIY battery packs.
Key Features:
Spot Welding Ready: Built-in alignment guides and indentations for nickel strips keep everything perfectly centered over the battery terminals during spot welding. This ensures strong, reliable connections and prevents accidental shorts.
Integrated Wire Routing: Designed with dedicated channels/holes to cleanly run balance wires or main power leads without making your pack bulky.
Quad Row Configurations: Includes 6 large sizes to build heavy-duty pack geometries: 4x2, 4x3, 4x4, 4x5, 4x6, and 4x7.
Thermal Management: Precise spacing between every cell ensures proper airflow, mitigating dangerous heat buildup during heavy charge/discharge cycles.
Printing Instructions:
Orientation: Print flat on the bed.
Supports: NONE. The wire routing channels are designed to bridge cleanly.
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 battery heat.
Infill: 20-30% (Grid/Gyroid) with at least 3 walls for maximum structural rigidity on these larger parts.
