I was unable to fold this flat; however, during that process of investigation, I found some other interesting folds.
I haven’t been able to visualize or physically find a way to fold a 120 degree angle with a flat layer below… the way the paper folds just doesn’t let that happen, as much as I want it to. maybe something more complex will make it possible, but I’m not sure what that would be.
However, I find that the more I try to work on attaining some specific goal, other things just seem to randomly pop up in the search. so I guess it’s all good.
