Twist and turn the handle on this lock to solve the maze hidden inside. My Lockpick puzzles are the result of my goal of creating a print-in-place puzzle that comes off the print bed ready to solve!
This is puzzle number 3 of 10. I tried to make it so the puzzles become increasingly difficult through the series, although they're all still on the easier side. If there's enough demand I can continue and make things more difficult :)
For ideal results, print at 0.15mm layer height. Other layer heights may make it difficult to snap the handle and lock apart. 2-3 shells and 5-10% infill should be fine. No supports. You can increase shell count if you're worried about the inner rod breaking, but I had no problems.
