I think I've worked out why adding super glue to my door worked.
Ideally a perfect door would have a smooth curve by the hinge but due to the molding most have a bit of excess plastic which jams things up a bit.
When I sanded mine it pivoted smooth but wouldn't lock in place.
A slight modification to the design would help make it so the door locks in place. It's basically what the super glue ended up doing.
Start of with a smooth curve then extend it slightly and end up at a flat section. When opening it will go smooth up until where it starts bulging then a bit of force will snap it to the flat section which will act to hold it in place. I've done a sketch to show the differences. The dotted line shows the original profile.

Dude… I recommend taking a second look at your pictures…
