Spoiler:There is an already opened up statue in the house. It's in the room where you had to open the suitcase with casettes. If you open the compartment, you'll see three thingies hanging down. I used that to work out the right positions of the sticks.
If that doesn't do it for you, read on.
They holes are arrayed like this:
1
2 3
4 5
6
If I remember correctly, the right combination is 1, 2, 5.
