Remember one month ago Italian police seized an extremely dangerous pla letter opener and a teenager's printer?
They're back
First they seized "a factory" of PLA knuckles: https://www.ildolomiti.it/cronaca/2026/un-15enne-e-un-13enne-producevano-tirapugni-con-le-stampanti-3d-della-scuola-hanno-anche-minacciato-un-compagno-che-voleva-denunciarli (a 13 years old kid printed multiple copies with the school's printer)
Now they went to the home of another middle schooler to seize his printer because he printed a prop from assassin's Creed: https://www.rainews.it/tgr/bolzano/articoli/2026/02/lame-stampate-in-3d-sequestrate-in-una-scuola-di-bolzano-eb67732d-a7a1-4eac-842b-a0bf7a87e937.html
I feel much safer now that those factories of dangerous weapons are now seized
Actually making weapons, plastic or not, on school equipment is a whole other level of stupidity well beyond regular 13yo idiocy.
Well yes, but also no. I went to school with a bunch of dumb asses who used metalwork classes to make "throwing stars", and half of them haven't been to prison yet.
I had an electronics teacher help me make "tripwires" to play a prank on a friend at school camp that would set off an airhorn once tripped, it was only after I finished he thought to mention "Don't use these to trigger anything else, and don't put the airhorn inside the tent with him."
Teenagers and sometimes the engineers who fall in to teaching them can be astoundingly dumb and work the challenge rather than think of the consequences.
Eh...your garage door has a "trip wire" type device. They're not just for traps.
He was aware of the use case. He was told in no uncertain terms what it would be used for and made suggestions around how to conceal the devices. I think we all know that there are certain people who will get so caught up working the problem that they often don't think about consequences til much later.
