All the files you need are uploaded here on Thingiverse. Every part I printed was scaled up by 6.6x because that fit my printer best. You can scale the files by any number you choose as long as it is consistent among all files.

I printed each part of the frame with 3 perimeter shells and 25% infill, but you can use the settings you're most comfortable with. The frame pieces can be printed in any color because they'll be primed and painted over later. Try to save one of the support pieces from an ear base. As shown in the next step this support piece is helpful for propping up other pieces as the glue dries.

The eyes and mouth need to be printed in white with 0% infill and 2 perimeter shells to make sure light can shine through. Be sure to adjust the eye model as shown in the second picture so that most of the cone is under the print floor, but there are still some "flaps" available to later attach the eye to the frame after it is painted.
