I've modified this model to use multi-color. The face and shoes have different colors. To achieve this, I used a relatively small purge tower, and the remaining purging was printed into the infill, which is not visible on the final print at all. (May warry with lighter body color)

If you're experiencing any sticking issues, feel free to use any type of adhesion method that works for you! Personally, I washed the build plate with IPA and soap to get the best adhesion possible so I did not need any additional adhesion!
