In this video, I test different 3D printing materials using the same open-end wrench design.
Of course, a metal wrench is the right tool in real life — this video is purely educational and focuses on material behavior, strength, and failure modes under load.
Using identical geometry, controlled print settings, and the same test setup, we can clearly see how different filaments perform when real torque is applied.
The goal is not to replace steel tools, but to better understand what 3D printed materials are actually capable of.
