(Edit 1 - Added Magnetic variant including a Blank Model, let your kids paint and draw their own. Uses 8mm by 2mm round magnets. Multiple mount points. I use the center point with an extra magnet on top the the Cozy Coupe screw head in center of the eye bracket.)

 My grandkids Cozy Coupe stickers were peeling, so I made new eyes from PETG. The Cozy Coupe has a small alignment ridge on it which I cut off to make these sit flush. Can be glued to the disk, or do as I did and use hook and loop (Velcro) so you can freely swap out different eye types. These can be customized with color and design. I will upload more designs for different styles later. I have reptile eyes, and even LED eyes (using battery powered LED inserts). Currently working on magnet version that is reliable, hope to add it soon as well. Feel free to make your own design and share in the comments. The grandkids love it.
