Igloo Latch stronger hinge
thingiverse
Original design was correct, I just beefed up the hinge a bit and got rid of the need for supports. The mount holes are 2" on center. When pinned it is a tight fit so the latch doesn't flop down and hit the cooler if the lid falls. You can sand it just a bit if you want it looser.
