I love one of the comments: > The fact my Lego, from when I was a kid, still fit and work with my kids new Lego sets, is a testament to the engineering.
I recently saw a video of building techniques for vegetation, it was not exactly the same but maybe it will help you, if I find it again I will post it here
I enjoyed the video, very much recommended, I always had problems with legs, I confirm that this way seems to be the right one, at least it generates very little stress, it's very smooth.
