Large Very Spiky Sensory Fidget Sphere

A large spiky sensory fidget for squeezing. prints in three parts and screws together to make a perfect sphere. I've upgraded the threads from the smaller version so that it screws together tightly. the spikes are also redesigned so they are equally spaced across the sphere and are very pokey. 

The one in the picture I printed with Red and Blue Dual Color Silk PLA which is really mesmerizing as it changes colors when looking at it from different directions.
