Happy New Year Iris Box

Starting with LoboCNC's wonderful “Print-In-Place Iris Box (locking)” I modified the model in 3 ways to make it work better. Now it's much more difficult to cause the iris fins to fall off.  It's robust enough to be a figet toy.

I also added the words “Happy New Year” to the floor of the box to make a very nice novelty new years gift.  

I recommend printing with 3 different colors: black, gold, and white. You must print with a 0.2 mm layer height.  Start with black filament. Change to gold at layer 9 (z is 1.8mm). Change to white at layer 14 (z is 2.8mm).
