Duplicate Key

A question came up as to whether or not a 3d printed key could be used in a real lock and this is my first try at answering that question. As demonstrated in the second photo it does actually work the lock (and was used multiple times) though I wouldn't count on it lasting long. It flexes considerably due to the spring tension. Quite a bit hinges on how much torque is needed to be applied to work the lock, but it certainly **can** work.
