Spinning Top Model

Hi, on my H2S there was a model for a spinning Top in 2 color/material. I printed one with black and glow in the dark blue and then my son printed a purple and black one.

The print worked nice the supports left some rough spots, nothing a file couldn’t fix. But there was another piece with it as well, and for the life of me I cannot figure out what it is. Can anyone help? Thanks everyone!

That’s not part of the model. That’s the prime tower. You can turn it off but if not it will make one when you do a multi-color print.
