Sorry but website with templates and plans is now down thanks to hackers and running costs.
Despite its looks this miniature keyring mouse trap is not dangerous. The springs not large enough to cause any real damage and the trigger teeth are not sharp.
This project took me a few attempts to get 100% right. It took 5 versions so this keychain trap is fun, safe, and easy to build. It requires no power tools at all and can be built from scrap, apart from the spring, which can be bought from eBay or made at home with piano or spring wire very cheaply. Having said that, use common sense and keep them away from very small children or pets.
