Key Lock Maze

thingiverse

Key+Lock with a Twist. Before inserting the key completely, you must navigate the maze inside first. This device can also be combined with a separate lever positioned beneath the maze lock or used as a fun challenge if you manage to get the key through the maze. I employed the top of the key from thingiverse: https://www.thingiverse.com/thing:2532059. Printed on 0.2mm layer height, infill isn't particularly crucial in this case. The cylinder doesn't require any supports, but the key may need some depending on its orientation. If there is sufficient interest in this project, I can upload the complete puzzle box I created for my girlfriend/soon-to-be wife :).
