I made this Puzzle Lock as an entry in the MakeAnything Design Challenge. It can be used as a normal lock, that can be opened with the combination (Or by force. It's just plastic!), or just as a puzzle. You can make your own combination, or just stick with the one i came up with. The puzzle Lock is both useful and fun.
Hope you like it, and please share it if you make it.
How to assemble:
Print the following pieces:
- 4 * 1x1
- 2 * 2x1
- Key (Optional: a screwdriver works as well)
- Place the 1x1's, 2x1's and Lock on the Base as shown on the picture.
- Strew og glue down the cover.
- Get solving! You can use the Key to easier move the pieces around.
Attention: Solving it you are free to rotate any part and note that the grid ontop is only there for holding the pieces in place.
