Hubba Hubba v1.1 (Parametric & Customizable hole adapter)

In my DIY & maker adventures, there are times when I just needed to get something to spin freely axially on a bearing. But for one reason or another, I'd need an adapter or hub to make the bearing work with whatever cylindrical object or hole I was working with. Enter Hubba Hubba!

Type in the dimensions you want for the two axles, how far apart they are, how hollow you need the thing, and boom! You got an item.

But that's not all! It's got other uses!
