Despite trying out various different settings, I was really struggling to get a working hinge out of PLA without the two halves fusing together.
I made an extremely quick edit to separate a single-part hinge into two parts for easier printing. Definitely room to improve and I can't speak for longevity as I haven't yet used my box too often, but at least it works. Printed with similar settings as stated in the original model.
Kudos to Pred_457770 for including the Fusion 360 file in his original design.
The author remixed this model.
Just the original box hinge modified into two parts.
