18650 Battery Holder Set | Wire Channels (2-6 Cells)

This is a practical set of spacers designed for building custom 18650 Li-Ion battery packs. The set includes linear strips ranging from 2 cells (1x2) up to 6 cells (1x6).

The Main Problem Solved: Standard spacers are often solid blocks. This design features dedicated triangular voids between the cells. These channels are perfect for routing BMS balance wires or inserting temperature sensors (thermistors) deep into the pack without wasting space or crushing the cables.

The Set Includes:

• 1x2 Holder

• 1x3 Holder

• 1x4 Holder

• 1x5 Holder

• 1x6 Holder

Key Features:

• Perfect Alignment: Keeps cells parallel for easy spot welding.

• Wire Management: Cleanly route cables through the pack structure.

• Modular: Combine strips to create packs of any width.

Printing Instructions:

• Material: PETG, ABS, or ASA are strongly recommended. PLA may deform if the battery pack gets warm.

• Supports: None required.

• Walls: 2-3 perimeters for strength.
