Customizable Fidget Stick / Spinning Axle
thingiverse
[EDIT] I put this back as a work in progress because I found that the connection between the nub and the stick didn't hold well with just hot glue with repeated use. I'll want to update it by changing the connection. Customize stick height and stick radius to make it longer or thicker for your needs. If you do, PLEASE share a make and let me see how it turned out!! This is a Spinning Axle apparently - according to this Indiegogo: https://www.indiegogo.com/projects/dawson-precision-spinning-axle#/ It wont cost you $170 though. I also added fillet versions that I edited in 123D to make a little nicer edges on them.
