popsicle stacking toy

HI, I'm new here in 3d printing. I am sharing one of my first project, mostly I try to do educational materials I can use for my students. Here is one of my finished projects, popsicle stacking, wherein kids can identify colors, associate it with flavors and make their popsicle how they like it. I am also open with suggestions on how I can improve my work. Thank you.
