You are the type of guy that burns his house down and then runs to the insurance company claiming it happened suddenly and once called out for blatantly lying you try to take a morale high ground because you lack the mental aptitude to admit that you fucked up.
Those rails don't break randomly. It broke because you shoved a jig in there and either used a faulty self-made one or did it wrong. I hope someone that knows you personally reaches out to amazon and tells them what really happened so that people like you don't get away with their bullshit.
how so agressive ? i've printed the 3d jig from schemas , and inserted correctly, without forcing, it worked great since the start without any issue, so i don't know what happened
and i am not a kid, i have 44 years old, and i buy always my stuff, so stop argueing please
