Flywheel Key Chain

I made this a couple of years ago as the intro project for a rapid manufacturing course I was taking. I had missed the first week or so of classes to go see the engines at the [Coolspring Power Museum](http://coolspringpowermuseum.org/) in PA. I did not want to miss any more classes and it was a Sunday, so we drove straight from PA to Atlanta and arrived home at about 4am. I had class at 10am, and the first project - a keychain - was due. I got a few hours of sleep and then headed to school to see what I could come up with. Sleep deprived as I was, and with the CPM logo and visions of 18' diameter 16,000 lbm flywheels still spinning around in my head, all I could come up with was this. I was lucky enough to have modeled up a flywheel for some model engines I was casting, so all I had to do was tweak that a bit and print it. I got it done just in time for class, and all was well.
