Master mailbox lock plug to discourage theft

thingiverse

Tired of thieves ransacking my mailbox and snatching important documents, I crafted this clever device that snugly fits onto the main mailbox lock.\r\n\r\nThis contraption is a real hassle to dislodge and the thief is looking for an easy target, so it's sufficient for now.\r\n\r\nDesigned to fit on 29mm diameter, 3mm deep locks, simply place it in position and push it with your hand, then finish the job with a mallet and you're done.
