Kubotan

Some friends at work were discussing Kubotans, and they asked if I might be able to make one on my 3D printer. I didn't see any on MakerWorld, turns out I spelled it incorrectly was why, so I hopped onto TinkerCad and whipped this up. This will fit a 1" key ring, and probably larger, but I have only tested it with the 1" size.
