With the help of the adaptor, a 13-mm wrench can be used to unlock a tringle lock. It was produced using a 0.4-mm nozzle and PETG. Five walls and 50% infill were used. With these specifications, it opened a tight lock without breaking. It is small enough to drop it to your socket wrench set. If it not fit it is easy to modify by the Fusion 360 file.
