Anna recently posted an instructional video on this model, and today I finally found some time to give it a try. The model is a bit harder to fold than I first expected, the collapsing is a bit tricky. I still decided to rate its complexity as "intermediate", once you've understood how to collapse it's not as hard anymore.
