Nirav Patel's successful RepRap printed house key test!
Imagine that one day, you get locked out of our home, but instead of calling the locksmith, or furtively smashing your own window, you call up a friend and ask them to print you a new one. Better still, you ask to borrow your neighbors printer, just for a 10 minute print.
Over at his blog, Nirav Patel has done some tests with his RepRap printer, and created a pair of OpenSCAD files that can parametrically be set to print any possible key combination of the two most popular US door key types (Kwikset KW1 and Schlage SC1). Cleverly, he didn”t try this in his door lock first try – having no desire to try to pick plastic out of his front door if the thing snapped off – but tried some second hand tumblers instead. He was successful!
