#2: Anti-Theft Lock
Phone chargers are hot commodity items in any home. It seems like someone is always in need of a charger throughout the day. It’s no wonder most of us constantly lose chargers or get them stolen from fellow family members. It’s pretty frustrating! Someone was so tired of his wife and daughter stealing his phone charger that he printed a special family-proof lock with his 3D printer.

This green gadget was specially made to keep his iPhone charger in place. It’s even screwed into the wall. This guy isn’t joking around! Forget simply buying two extra phone chargers. Designing and printing a special gadget to prevent sharing is the way to go. We love the level of pettiness.
