Bolt Lock Locker

thingiverse

There was once a clever gadget featured on TV infomercials that you could easily slip over a standard door bolt lock, effectively immobilizing it even when someone tried to open it with a key, pick, or bump tool. Online forums, such as Reddit, were buzzing with discussions about how this device could be easily created using a 3D printer. The rear plate of this innovative gadget is an impressive 2mm thick. This should provide ample clearance to fit behind any standard bolt without issues, and it's simple enough to scale the design thinner or thicker depending on specific needs for a snugger fit or added strength. The 'plug' component can be securely attached to the door via screws, providing a solid grip (thanks to the large round handle hole) even if your door lacks an extended frame.
