Insoluble Cipher Lock/Cipher Toy

A puzzle lock that can be used as a lock, but you might not be able to unlock it yourself, requiring some skill. I will create a document for the specific installation and unlocking methods (unlocked by adjusting the lock core notch and pin position). I look forward to you printing and trying to unlock it (for learning and exchange only)

Note: Recently, many people have reported issues with the lock core not coming out. This is likely due to the use of different filament materials or brands, leading to a stronger bond. The lock core only needs to be lifted slightly to move up and down a small distance and be able to rotate; it does not need to be completely removed. That's how it's designed. If it doesn't budge, you can use a bit more force!
