Did you have easy access to 3d printing? It was possible to build your own guns with other tools, but they’d all be a lot less common and more dangerous for a 14 year old to use.
No argument here. I’m persuaded that the quantity indicates something more than just test prints; maybe he was attempting to build multiples for testing purposes, maybe it was in case he screwed one up during assembly and didn’t want to wait hours and hours for another one to print, maybe a lot of things.
