I want to make a fuss about this because I just found a large amount of these pieces broken on my sets and I'm pretty frustrated about it, and I've never seen anyone else talking about this.
Technic axle connectors such as bushes (3713), cross-axles (32039), double axle connectors (32184), (really anything with an axle connection similar to the bush's design) are some of the most brittle objects ever created by mankind. I primarily collect Bionicle sets which have a lot of these Technic pieces, and for as long as I've built and played with them they've been a big problem. Even the 2015-2016 sets had these issues, in fact they were the worst offenders for whatever reason. I'm not rough with them or even build anything anymore, but just from very mild play and occasional posing they consistently crack and it's just ridiculous how fragile they are. I'm paranoid to even breathe near some of these sets now because I don't want anything breaking apart.
I don't even understand some of these pieces, such as 32039. Why is a part that's meant to sturdily hold axle rods in place so thin and fragile? Meanwhile a piece with an identical purpose, 32013, is thick and strong and never breaks because of it.
Am I just extremely unlucky or something? Does anyone else experience these problems?
