Roller for Strong Pulley - customizable

I really like [Strong pulley](https://www.thingiverse.com/thing:6368467/) by Anton Edelmann.

And I really like the idea of having [different pulleys gaps](https://www.thingiverse.com/thing:6393211) by Mikhail Vedekhin, but I wanted to add some "gears / notches", and being able to customize gap between central parts.

So here it is: an online customizable version (thanks to Onshape):

Once you're happy with your customization, select "int" and "out" objects, right click and select "export", then in format select "STL"
