Spinning Tops

For this assignment I was tasked with designing a spinning top. 

I designed two. 

The biggest challenge with these projects were keeping thing concentric. The first top I designed was easy to spin but isn't completely concentric so it has a persistent yet slight "wobble"

This second Top I was able to keep very concentric and when spun stays up for a very long time, but it is difficult to get spinning because of how low the skirt is.
