Puzzle Cylinder

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4799848.

Navigate the hidden maze by turning the two dials.

Print in place, fully assembled - optimized for 0.2mm layer height. Run a sharp edge around the seams to separate the dials and internal sliders if necessary.

As for the locking mechanism, it prints in the "unlocked" position. Without giving too much away, to lock it turn the top dial 180 degrees before turning the bottom dial to engage the "maze" mechanism. Entering the maze is deceptively easy, escaping not so much.
