“Twin Lock Box” is a wooden combination lock puzzle box that I designed. I applied the mechanic of my “Tricky opening bottle” to this box.
This puzzle box has five keys on both side. You must push all wooden keys to correct position for opening the box. After opening the box you can change order of keys and you can make your own box configuration.
On both side of the box there are 5 wooden sliding key. Each key has two position and can move until the borders of the box. After opening the box you can remove all keys and you can make your own configuration by changing their order. If your friend have the same box, he can't open yours.
This puzzle box has three main section
1. Wooden keys
3. Box cover
I started to make this puzzle by making wooden keys. After I made box and box cover.
The overall dimensions of this box is about 70x82x150 mm. But I advise understanding the design and making your box according to your materials an the dimensions. This is a simple design for converting dimensions.
