Somewhat back on topic, I've been thinking of building a fold-back retractable ABS-GF cover for my phone mount that I can just pull forward if the sun is cooking the delicate internals of my iPhone. I found this snack box which is more or less what I'm trying to duplicate, but what the hell would you call this style of print-in-place retractable hinge? I've tried everything I can think of, and this is the only example I could find. I've tried all sorts of things like armadillo hinge snail shell half shell roll top retractable cover ?????? https://makerworld.com/en/models/1457658-armadillo-snack-box-print-in-place Would like to find one that only folds 90 degrees or a little more, but I don't know what the hell to search for to get similar results.
