Very customizable key safe

thingiverse

A small safe to hold a key behind a numbered lock. It's easy to get the key out if you urgently need it, but obvious after the fact when the unique lock is broken. Remixed from a previous design to make almost every dimension parametric and customizable. The text can be different on both sides, and this can be customized to support many different shapes and sizes of keys. There are lots of different sources for numbered tamper-evident tags that can be used to lock the key in place - a search for "Plastic Security Seal numbered" will reveal those sources. This new version can also support keys with offset holes. A sample STL file is included that demonstrates that. The .scad source file is included. A single STL file is included with EMERGENCY written on both sides. However, it probably won't be the perfect fit for your key -- so fire up the customizer and parameterize to your hearts content. It will help if you can measure your key especially with some digital calipers so you can enter the values correctly.
