Simple connection for attaching googly eyes to a pom pom using a pom pom maker. The googly eyes I used were approximately 15mm in diameter, but the model can be scaled up or down to accommodate eyes of your choice.

The model can be printed without supports at its current scale with the recess for the eye facing downwards.

To attach, finish making the pom pom as normal, then use the two leftover tail ends of yarn from the central knot to tie the googly eyes to the pom pom, being sure to make the knots as close to the center of the pom pom as possible.
