This kaleidoscope uses the poop generated by the 3D printer as the medium to generate the image.

It consists of four 3D printed parts that screw together. In addition, (2) pieces of 55mm(2.18") diameter clear plastic and (3) pieces of 43mm X 200mm (1.71" X 7.87") mirror are needed.

The clear plastic can be cut from an empty jar (such as peanut butter) and the mirror can be obtained online. I used mirror from Amazon.
