These little guys are the Tri-Bunnies. They only have three sides and are my simplest to build models yet. I wanted to make something for the younger folks that would be fun to play with yet easy to build.
You can download your very own Tri-Bunnies for free here and print them on card stock or matte photo paper.
P.S. If you do build one of my models and would like to take a picture of it and send it to me that would be great. I'll put them up on my flickr account.
