Articulated Snake

I used Tinkercad to design the snake.

I started with the hinge I had originally. I enlarged it and added more space to allow for more movement as my gingerbread man was my first time trying the hinge and it didn't have much movement.

I used the snake body (which was really a cylinder with flattened top and bottom to help with printing) from my previous project to create a negative of it. I used this to cut the hinge to the right shape.

Because the hinge was the exact size I needed, instead of adding the hinge to a design, I just copied and use the hinge segment along with the head (elongated sphere with spheres for eyes) and tail (paraboloid) to make the snake!

Also because it is made of segments, you could make it as long or as short as you want easily. Just add or remove segments.
