After a few iterations and testing some already made models from other creations (thank you), i came to the conclusion that i needed to start one design myself and this is the result.

This model is not much different from the ones already available, but the spring needed more play for my taste and it had to print fast because kids use, kids break! And if it breaks, you can print another pair in minutes.

Since these are googly eyes, there isn't much to do in regards to the model because they all share the same thing, the Eyes.

Assembly is done by pressing all parts together or, if your printer is not 100% calibrated, and just to be sure, add a little bit of super glue to the center hole in the black part of the eyes and press against the white eye part it until it's glued.

Scaling is already made and tested. Scaling smaller than the smallest size that is already on the model will not work, i am almost sure. If you scale smaller than this and it works, let me know.

Have fun and put those eyes everywhere!
