key and lock 3D model

cgtrader

This is a lock that works with a special key. You can see how it functions and assemble its parts on your own. Even if you have some experience with 3D design, you can easily create your own key. This model isn't just a concept; you can print the lock itself to use for securing doors, drawers, or any other case that requires locking. I must note that this lock was designed specifically for plastic materials, which resulted in some changes to its proportions to ensure it works effectively and lasts longer.
