Adjustable Fidget Spinners

I saw this article, [Those Darn Spinners are Going to be the End of Me](http://matthewmccullough.weebly.com/blog---mind-wanderings/those-darn-spinners-are-going-to-be-the-end-of-me), the other day. This got me to thinking and wanting to play.

Here are a couple of fidget spinners that I designed to make experimentation easy. I'm using fender washers for weights. Each spinner can accommodate a variable number of washers. The one that looks like a Tie Fighter also allows you to position the washers varying distances from the center (you'd need an extra set of nuts though).

I used [standard skateboard bearings](https://www.amazon.com/gp/product/B00NX1WBA0/ref=as_li_ss_tl?ie=UTF8&psc=1&linkCode=sl1&tag=fl0d3-20&linkId=452b422693748b61823596cba924f3e8). The grease causes these to slow down too quickly so I dropped them in some Acetone first (a quick google search will show you many ways to degrease bearings). I also found they spin longer of I popped the metal covers off. All the YouTu
