Combination Padlock

SummaryThis 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, so it's not for high security. This is not mine. This is by BCaron on Thingiverse.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 combinationsSelectable security options: 3 or 4 tumblers with 6 or 10 digit numbersSpring loaded detent feature on tumblers for precise positioning and satisfyingly tactile feedbackSimilar dimensions to classic rotary Master Lock for compatibility with most lockers and other latchesStrong lock body and shackle that resists forcing openNormal or long shackle options for securing larger latchesSolidWorks files for your own customizationv2 Improvements:Print-in-place springs for detent works far better than old design which would break after a whileOption for 3 or 4 tumbler lock and 6 or 10 digit tumblersThreaded cap eliminates glue and allows for easier changing of combination.Taller wall next to shackle latch better resists forcing open of the lockFlipped tumbler position for easier right-handed operationTumblers can now be printed without supportsVarious changes to make printing easier and cleaner
