Lock-Jamming Key

thingiverse

This key exploits the design of tumblers inside standard household door knobs to become locked in - rendering it impossible to remove and effectively ruining the entire door knob. WARNING: This is purely a proof-of-concept exercise, and I strongly advise against using this key to ruin someone's day. If you're determined to destroy a lock, do so at your own risk - on your own property. Don't say I didn't warn you if you end up locking yourself out of your house. Print Settings Rafts: None Supports: Yes Notes: To achieve optimal results, print this key as solidly as possible. Avoid using a Raft or Brim; the consequences will be regrettable.
