I'm tired of spinners, they had their day and it's gone. But since I previously shamed myself by posting one, I had to get this last piece out of my archive and off my chest... The Wobbler. This wobble core swaps out readily with the regular centered core in the Magnetic, Interchangeable Spinner. https://pinshape.com/items/105... No, it's not perfectly balanced, the center of this core is off by .040" or about 1mm.  Put this into the spinner and it will wobble madly.  So much more interesting than a centered core.  Maybe I like it because I relate more to the wobble core, we speak the same language. You're welcome, and I will say no more about spinners, my shame is now complete. Mark
