A New twist on the popular impossible passthrough fidget toy!  How high can you stack them? These are designed to be stacked on top of each other and the reverse twist vortex spiral will travel through the whole stack! 

These are printed upside down on the build plate so no supports are needed.  If the fidget does not pass through on the first try, just insert the fidget in and out about 10 times or so, to debur the edges.
