How much cash are we talking about? Even just googling that for a few minutes I found this site that shows an ad for a Glock switch for $36, but the text says you can get them for $18.
Budget 3d printers start at around ~$200 new, and are a lot cheaper used. But lots of kids have 3d printers, or access to one, so he might not even have bought it.
So for all we know it’s a switch for 18 bucks and some filament. He might just have taken the filament from his father’s workshop, or stolen in a shop.
But if the kid has access to a 3d printer and is savy with a computer, he has lots of ways of making money, or he might just do odd jobs here and there, or saved up his allowance.
The “high-end 3D printers” shown in the photo are from Elegoo, you can clearly read the label, and they look like the pre-owned Neptune 3 Pro Elegoo sells on their website form $103.
Anyone with access to a web browser can order shit from China. With a gift card you can do that from any internet cafe. Most kids just do it from a smart phone, because Screen Time and that Android thing has plenty of loopholes. .
This is pretty easy to figure out. There is a huge overlap in intelligence between clever 14-year olds and adult gun nuts who buy that crap.
For all we know the tools were his father’s, and and the alleged intent to sell firearms is just the usual bullshit police makes up to look important.
I can’t understand why this topic would incite so much wild speculation?
The article states that they’d have to prove the intent to sell those weapons. Not that he made weapons.
