This is a single wheel finger fidget board that you can play with, to some degree, like finger skate boards. It fits together with one snap connector and a friction connection (see photos). This design started out as an experiment in connectors, but it seemed to make an interesting toy. I modified the original design to make it more finger friendly. Since it doesn't incorporate steel bearings, it doesn't roll as smooth as if it did. It is kind of amusing to play with. You can also use it as a mini roller massager if you have tennis elbow. :)

I have included the three pieces as separate object files, and one file combining the three pieces, if you want to print them that way. Be sure to print the axles in their normal orientation for added strength. Print the wheel/tire laying on its side.
