For our 3D-printed puzzle, we are using the character models from my game, “Mekazoo,” to create a totem pole.  As seen below (assembled & disassembled,  Each model has a square hole through it so that all the models can fit over the base, creating a “totem pole” of animals.  I also created small indentations on the back of each animal (using the animals as “holes” slightly embedded in the animal below it’s back) to hopefully allow the pieces to fit together more smoothly.  We’ll see how it all works out once we print it out and assemble it!
