Making holes into the wooden structure

After finishing the laser cut for the structure, I made holes in 2 different sizes for the piece.
1 size for the 5mm thick wooden sticks, and the others for the 1,5 mm Sate wooden sticks.

The place of the holes was not really Random, but more in groups and families.
The places of the big and thick wooden sticks is in the middle,because in reality all the thick trees also in the centre of the jungle and lake.

the thinner wooden sticks are in at the ends of the piece.
