4 Digit Counter

4 Digit Counter with integrated springs that has a nice audible click when turned, inspired by others I've seen and those fidget clicky toys, it doesn't need any extra parts, just a bit of lubrication but I've found that you can just use your skin oil so before assembling it grab the rings with your hands and make sure to touch the surfaces that make contact. I also made a two digit and a single digit version.
