Looking for a sharp pokey fidget for sensory regulation?  Look no further!  

Now available in three sizes, ~30mm, ~40mm, and ~50mm.  Prints in two halves with a post in the middle.  Does NOT need to be glued.  Use a washcloth to help squeeze the halves together to protect your hands.  

V2 - this uses a trapezoid shaped post to make it easier to line up the spikes when you assemble the balls.
