32140 Cell Holder Inserts (M3 Threaded) / Brackets & BMS Mounting

32140 Cell Holder Inserts (M3 Threaded) / Brackets & BMS Mounting

Custom-designed inserts for standard 32140 LiFePO4 battery cell holders.

These inserts allow you to:

Connect individual cell holders together into a rigid, custom-shaped battery pack frame.

Mount external plates (acrylic, PCB, or 3D-printed) directly onto the battery module to attach a BMS (Battery Management System), fuses, or wiring channels.

The insert features a center hole designed specifically for tapping an M3 thread (or using self-tapping M3 screws / heat-set inserts if resized slightly).

Key Features:

Fits standard 32140 LiFePO4 plastic holders.

Designed with a pre-sized hole for direct M3 thread tapping.

Enhances structural integrity of assembled battery packs.

Easy to print, low material consumption.

Print Settings:

Material: PETG or ABS/ASA recommended (for higher temperature resistance and toughness around battery cells), though PLA works for lightweight applications.

Infill: 40% – 100% (higher infill ensures stronger thread retention).

Layer Height: 0.16mm – 0.20mm.

Walls/Perimeters: 3–4 perimeter lines for solid thread walls.

Supports: No supports required.

Post-Processing / Assembly:

Insert the printed part into the designated slot on your 32140 cell holder.

Use an M3 tap to cut the thread into the central hole (or carefully drive an M3 machine screw in).

Secure your BMS mounting plate or structural link using standard M3 bolts.
