HOWTO make a working, lockable papercraft safe

JD sez, "This site provides complete plans for printing and assembling a single drawer safe protected by a three digit combination lock."

Paper Safe : Come and get it! (Thanks, JD!)



  1. I know it’s intended for novelty purposes only, but it reminds me of the Japanese prison in the Simpsons where, after being freed, Homer walks right through the ricepaper wall.

    1.  If you want it to be a bit less of a novelty/demonstration, you could redesign it in plywood…

  2. Ha! It may be lockable but I’m pretty sure I could break in to it in less than an hour. Maybe two.

    1. Then you will face the humiliation of being arrested and escorted to the station while wearing Chinese finger cuffs.

  3. There was a web hosting company in Chicago that spent tens of thousands on security – biometric identification, multiple levels of steel security doors, database logging of all entries and exits, etc.
    Somebody took a sledgehammer and smashed through the drywall and stole a bunch of their servers.

    This piece is brilliant BTW. It’s functional too – it won’t keep anyone out, but it will let you know if they’ve been in it.

  4.  Speaking as locksmith: This is a valid model of an older/basic version of the traditional dial combination lock mechanism, still in use in some cheap devices. Better versions, of course, employ various additional mechanisms to protect the lock from attempts to figure out the combination.
