Working Combination Padlock - Custom Code - Kit Card

Build a working combination lock, then set it to any code you want. It arrives as a flat card of parts. Five minutes later it's a padlock that locks. Set the three dials to your number and the shackle lifts out. Get one wrong and it won't budge. The dials don't click — they're a press fit, so they turn under your thumb and then sit exactly where you left them. Nothing drifts off your number. The code is yours: 27 dials come with it, three each of the digits 1 through 9. That's any of 729 combinations. Pick a birthday, pick a lucky number, pull it apart and change it next month. 30 parts, no tools, about five minutes at the table.

Good on a lockbox, a diary, a treasure hunt, or wrapped around a gift someone has to earn. It's a puzzle and a desk piece, not security hardware: it'll keep a sibling out of a box, it won't keep anyone out of a shed.
