Here's a nice and embarrassing story: German hacker Ray, who is well known for opening handcuffs, has photographed the official handcuff key of the Dutch police, modelled it in Blender and printed it on a Reprap 3D printer. And guess what? It works!
He used a 3D printer to print handcuff keys. And not just any ordinary handcuff key â€¦ no, it's the official handcuff key from the Dutch police! At first the police officers at HAR were a little reluctant to event try out the plastic key he printed. But he found another way to verify the key he printed was the correct one. I guess these officers never thought about wearing keys concealed, especially when talking with Mr. Handcuff himself. Given the megapixel camera's on the market today it was not so difficult to verify the key he printed was the correct one.
These keys are 'only sold to government agencies'. Well, fat lot of good that'll do them now ;-)
Check out the first line in the STL file to see proof it was made in Blender.
