The oriental toothpick safe

This pretty old puzzle (well it's from 2001, so 14 years ago!) was designed and made by Frank Chambers, with the usual material he used for puzzles: corian.

A pretty small puzzle and a quite heavy one regarding its size. The 3 colors of the puzzle are simple but well chosen in my opinion.

There are 2 goals: first one is to open the puzzle, second one is to make a shape with the toothpicks inside (thus the name of the puzzle).

As you can see on the lid is a black button, you can remove it if you want to see the mechanism. It should be glued but it's up to you if you want to glue it or not. I think better not so that you can admire the mechanism many times. And I feel always frustrated not to be able to see the mechanism for some puzzles.

I did not spend long time before managing to open the puzzle. Actually it's not a difficult puzzle and the mechanism is pretty simple, but well implemented.

For the second goal of the puzzle: making the shape with the toothpick is much more difficult.
Well, I would even say it's fetched, very fetched! And even the solution kept me thinking for some time why this was the solution!...It's a strange solution but yes in reality it would work...
You have to really think out of the box to understand it!

Would this hole give any clue?
