shelf wall tree

I made this for my 4 year old son to have a display wall in our living room for his legos. I made the platform and the support without top or bottom walls and a hexagonal 10% infill. Turned out great. When I first told my wife I 3d printed a display shelf for this purpose, she gave me that "I know I'm not going to like this" look. But turns out my wife really likes this design! WIN!
