Please help me model this so i can extrude and 3d print eventualy


I want to model the following in 3 different parts so i can multi color 3d print it. Just the circles.

You want the red, yellow, and black parts separate pieces? Are they 2D like they appear in the image?

If so, use the black object to cut away the yellow object with a boolean. Then temporarily Join these two and use them to cut away the red object with another boolean. Now un-Join the black and yellow objects and you’re done.
