BobbleHead Kenny


This project had a fairly simple inspiration – I watch a lot of South Park and I am a big fan of the character Kenny. For a majority of the show, he is killed every episode and then reappears the next episode like nothing happened. Later in the show, we find out that this is his superhero power and he wakes up in bed totally fine the next morning every time he dies. I thought making a bobble head would be an interesting take on the motion assignment, and Kenny is a fairly simple character as he is basically just an orange blob in a hoodie.

Final Object



To figure out how I would make a bobble head, I first looked at a bobble head that Professor Plante had. I saw that there was a spring connecting the body and head. I decided to create a post on the body that was slightly smaller than the small end of the spring, and one that was bigger than the larger end of the spring on the head. The spring I chose to use has a one end that is much larger, so I figured I could glue that directly onto a post in the head and it would support the weight. I wanted the smaller end of the spring to wrap around the post on the body so that it would hold sturdy.

I made the rest of the body fairly simple, with some detail in the face. I did this so that I could focus on testing the functionality of the project. With my current scale, everything is way too big to print. To fix this, I will find a smaller spring so I can scale everything down. I would assume there is a limit to how large you can make this due to the weight of the head (unless you had a really strong spring). I will figure this out by doing test prints for different spring sizes.
