I've taken pictures of all of my winning level configurations, but that may not directly equate to beating the levels for you. I found that the way things fall, the monkey's effect on the sticks, and the final outcome of the level are non-deterministic. I would occasionally beat a level without changing anything - just restarting the action seemed to make it work. So, take the pictures as a starting point,a nd adjust them as needed to get to the winning combo.
For the pictures, they were taken after I beat the Eco challenge for each level, so they will show you how I got this achievement. Also, some levels needed two pictures, so you will see some a/b pictures. a is generally the top of the level, and b is the bottom.
