When I saw the original design, I thought that it would make a great key chain for my daughter (she's 30 but still loves dolphins). I reduced the size by 50%, and added the key chain hole. I was worried about it being strong enough (the first layer in parts was only 1mm thick), so I doubled the weak spots to 2mm. I also reinforced the dorsel fin (my daughter broke her's in less than an hour) and the tail as well. I did not do as well as the original design but it works.
