This adapter is intended for use with non‑original, lower‑capacity Battery. It is not a replacement for the official WOLFANG GA420 battery. Always verify correct voltage and polarity before powering the camera. The creator is not responsible for damage, malfunction, or reduced performance resulting from the use of third‑party or low‑capacity power options.

Battery Insert Adapter for WOLFANG GA420

A custom‑designed battery insert adapter made specifically for the WOLFANG GA420 action camera. This insert allows you to power the camera using an alternative battery setup.

When purchasing the GA420, there were batteries advertised as compatible — same brand family, same voltage, and similar capacity. However, the replacement battery available at the time was a different physical size, making it impossible to use directly in the camera. This STL provides a practical solution: an insert that fills the battery compartment and allows you to route power from an external or differently sized battery safely and cleanly.

Features

Precise fit for the WOLFANG GA420 battery compartment Clean internal channel for routing power leads Snug, stable insertion with reliable tolerances Compatible with both FDM and resin (SLA/DLP/LCD) printing

Printing Notes

Do not use PLA — the GA420 is known to run warm, and PLA may soften or deform

Recommended materials: ABS, Nylon, or PETG for heat resistance and durability

Use a 0.2 mm nozzle (or finer) — the walls are thin and benefit from higher precision

Print with 0% infill — the model is designed with thin walls and does not require internal structure

Standard 0.2 mm layer height for FDM

Resin prints offer excellent dimensional accuracy

No supports required (if true for your model)

Depending on your build surface, a brim may be needed — the main wall is thin and benefits from extra adhesion

Slow print speeds recommended: around 50 mm/s for cleaner walls and better dimensional accuracy

Approximate print time: around 10 minutes at 50mm/s

Material usage: roughly 20 g total
