Q: Is my 3D printed plastic bullet proof vest REALLY bullet proof?
A: Ah, no. It's more like bullet "maybe" proof. The plastic is nice, but it's no match for actual bullets.
Q: But I saw it in a YouTube video and the dude in the video was like, "This thing saved my life!"
A: That guy was probably just trying to get more likes. Or he was just really, really lucky. Either way, don't try this at home, kids.
