Onion - Fidget toy

I saw thing:423597,
but it was just a .STL,
As i wanted to modify it I made this OpenSCAD model.
So just to show off, and to help new members in my local Hackerspace:

You can change diameters, wall thicknesses, gap,number of layers.
so you can tweak it for your printer,
Enjoy

Oops forgot OpenSCAD file :(
