YUN made such a cute model, and my nieces loved it. But there were a couple of places that could use improvement for durability. I strengthened the hinge, and got rid of a couple of small bits that easily break off. The hinge snaps together quite easily now but I still put the bottom of the hinge in hot water for 10 seconds before snapping it together, just to make it go together super easy.
The author remixed this model.
I improved the hinged area to make it easier to put the two pieces together.
I improved how the helmet sits on the body, so there are no tabs to easily break off.
And finally, I moved the spot the helm splits from the body so that there are no delicate pieces to break off as the kids play with it.
