This is a working combination padlock design that can be used in place of a standard Master Lock on a locker or whatever. It's relatively strong, but it is plastic it's, so not for high security.

**UPDATE 8/22/2024:**
- Fixed the body models adding more clearance around the detents and springs. Use **Body_FIXED.STL**. This should resolve the printing issues many people are having.

- Added an option to print the springs separately if you prefer. The springs work quite well this way and should be easier to print successfully. Use **Body_noSprings.STL** and **Spring.STL**. Updated instructions are below.

**Features:**
- Configurable combination: up to 10,000 possible combinations
- Selectable security options: 3 or 4 tumblers with 6 or 10 digit numbers
- Spring loaded detent feature on tumblers for precise positioning and satisfyingly tactile feedback
- Similar dimensions to classic rotary Master Lock for compatibility with most lockers and other latches
- Strong lock
