Can you imagine how this 3D model rolls please try it 3D print model

It has geometrically interesting shapes and movements.It rolls down a slope while swinging from side to side like that in a video below.

I developed a special software for modeling this 3D model. General 3D modeling softwares can't guarantee a constraint that designed 3D models rolls like printed 3D models in a video.

It is difficult to predict how it will roll at first glance and it is entertaining to watch it move.I recommend it as a interior, a toy for kids. I hope you enjoy it.
