Cinco hand spinner fidget

There are a whole bunch of hand spinners here, but most of them have three outside bearings. That's all well and good, and really works quite well, but when you get a 10 pack of 608ZZ bearings from Amazon and make your triple spinner, you have six bearings left. While that's enough to print two double spinners, what fun is that? The only purpose the outside bearings really serve is to increase the rotational inertia of the spinner - so why not go bigger?

Honestly it doesn't work as well as a triple spinner for the general use of fidgeting - the geometry doesn't feel quite as good - but because of all the added rotational inertia, it sure does like to spin. For end buttons, I'd suggest using the already excellent ones from the one I listed as a the remix source.
