As we speak 14 year old boys are hand-making AK-47s that work like a charm in small rooms in Pakistan and elsewhere.

One of my 10 year olds is making a Lego machine gun, tied to Lego EV3. Looking to next mount it on a mobile platform and program it via a Raspberry Pi and Adruino. Fun, educational, not deadly like an AK-47. We've got one of those, too.

Wonder what he or his twin brother would build if given a fully functional 3D printer?
