My filament colors are a bit off. The colors should be red, white, and cyan/light blue. A fine tip permanent marker seems to work for the labeling and, if you want, drawing in the face. I've included built-in supports for the few parts that needed them. In order to align the parts, I've left a slot that accepts 1.75mm filament. The slot is 2mm, but you may need to open it up using heat or a file. It can close up due to first layer flattening. "And then he was gone With a tip of his hat."
