18650 Battery Spacer Strips | Octagonal (2-7 cells)

BOM: Printed with ROSA3D High Speed PLA Dark Blue

Build professional custom Lithium-Ion battery packs with these precision spacers. This set focuses on linear strips (1 cell wide) ranging from 2 to 7 cells in length.

Smart Octagonal Design: Unlike standard round holders, these feature an octagonal (8-sided) profile for each cell. When arranged in a square grid, this geometry intentionally creates gaps between the cells.

• Wire Routing: Provides clear channels to run BMS wires or balance leads between the batteries.

• Airflow: Improves cooling by allowing air to circulate between cells.

The Set Includes:

• 1x2

• 1x3

• 1x4

• 1x5

• 1x6

• 1x7

Printing Instructions:

• Material: ABS, ASA, or PETG are highly recommended for battery packs due to their heat resistance. PLA is only suitable for low-power applications where the batteries won't get hot.

• Fit: Designed for a snug friction fit. Depending on your printer's flow rate, you might need to scale X/Y slightly (+/- 0.5%) for the perfect snap.
