This version constructed with shape profiles from inkscape.
Three versions premade for you 50mm, 80mm, 100mm diameters.
The Customizer will allow you to create the size you want.

The wall thickness is 1mm when the Spinner is 50mm wide.
The ideal size is 80-100mm in diameter. But seed beeds are small :).
Will work with any round bead with holes.
