JBL Charge 3 Battery Cover Replacement Reinforced

If your JBL Charge 3 speaker has a swollen or damaged battery, chances are the original battery cover has cracked or broken. This is a common problem because the OEM cover is thin and not designed to handle swelling over time.

This 3D printable replacement battery cover is designed to fix that issue:

🛠 Direct replacement for the stock JBL Charge 3 battery cover

💪 Reinforced design for more strength and durability compared to the original part

🔩 Easy to install – uses the same screws and mounting points as the OEM cover

🧹 Keeps the battery compartment protected from dust and debris

Printing recommendations

Material: PETG or ABS (recommended for heat resistance and toughness)

Orientation: Flat on the print bed

Notes ⚠

If your battery is swollen, replace it as soon as possible. This part is meant as a repair and upgrade, not a substitute for a failing Li-ion battery.

Works only with the JBL Charge 3 (not compatible with Charge 2, Charge 4, or other models).

Differences of the remix compared to the original

The original model is meant for printing in translucent filament. But I don't have so if I print the original model the charging LEDs won't be visible. I modified the model so you can use opaque filament and the LEDs still be visible by hollowing the LED area.
