I used the 3mm material thickness plans. After a little arranging, I was able to get all of the pieces cut, cleaned, and assembled. The only thing I don't like about this design is there is very little area to glue the box together. On the plus side, you don't "have" to use glue and for the most part, the box will stay together while just sitting. I like the simplicity of the hinge. It works much better than I expected and I will have to incorporate that into my own designs.
