Experiment of structure

Before making model using 3d program, I drew some sketches and tested the shape and structure.

[Sketches] 

This sketch was inspired by geometric mobile.
The structures are combining the main face every time when it rotate.

Alternatively work structure with 2 cogwheels.
It could be possible to make an object which rotate 2-way by attaching faces on the cogwheels.

This structure is composed of two squares which rotate and move at the same time.
I want to make 3rd sketch among the above things, but when I tried to make that by hand, the back side became too complicated to combine together. In the end, I failed because these faces couldn't support the movement.

For this reason, I just tried to make a simple structure for practice using Pepakura and projection.

For my object, I used 3dsMax program to design it.

Export .obj file and then unfold in Pepakura.

Completed!
