3D printed lock

thingiverse

This is a 3D printed lock with a larger compartment than my previous lock design. Inside, four pins can be 3D printed to fit snugly within it. To bring this design to life, additional components are required: springs that will rest above the pins. These springs should have a diameter of exactly 5 millimeters and a length between 15 and 20 millimeters. For spring-loaded drawers, two additional springs with diameters ranging from 6 to 8 millimeters and lengths between 10 and 25 millimeters are necessary. Furthermore, four M3 screws and nuts will be needed for assembly. Within the drawer itself, there are two holes designed specifically to accommodate two 4 millimeter pins of length 10 millimeters, which can help prevent the drawer from jumping out prematurely.
