This is the "Triple Row" heavy-duty edition of my battery holder set. It covers grid configurations from 3x2 up to 3x6, designed for building larger, high-capacity battery blocks that require maximum structural rigidity.

The Main Advantage: With three rows of cells, these holders create a very stable core for your battery pack. Like the previous versions, they feature dedicated internal channels in the diamond-shaped gaps between cells. This allows for professional routing of BMS balance wires or the insertion of thermal sensors deep into the pack's core.

The Set Includes:

3x2 Holder (6 cells)

3x3 Holder (9 cells)

3x4 Holder (12 cells)

3x5 Holder (15 cells)

3x6 Holder (18 cells)

Key Features:

Heavy Duty: Triple-row grid offers excellent mechanical stability.

Smart Wiring: Routing channels keep your pack organized and safe.

Modular: Combine with 1x or 2x strips to build complex shapes.

Printing Instructions:

Material: PETG, ABS, or ASA are recommended for heat resistance.

Supports: None required.

Infill/Walls: 3 perimeters recommended for extra stiffness.
