A-Maze-ing lock

thingiverse

This is a very fun and interactive project. It is great as a present or toy. Everything was printed and tested. Version 1 is easy as you can see the maze, but 2 and 3 are inverted so it is harder to solve. The key is hollow to put messages or small presents. (20mm diameter) Cool way to give messages to friends if you want them to have a tough time opening and reading. All 3 designs have the same maze structure. Only the outside is different.
