I designed this articulated mouse with a pet toy in mind.
You can place a small bell during printing, that will make it more attractive.
Take a look at the video: https://youtu.be/cJqqdefZYb0
If you are going to use it as a toy with an animal or small child, I recommend printing it with flexible filament so they don't get hurt and resizing it to the right size.
It is printed without additional supports.
