I’ve seen a few other spinner designs posted lately, I figured I would throw my “inspired” design in the ring as well. I have also uploaded the file to Thingiverse for anyone that wants to recreate one for themselves.
They should (retroactively, as well) give these out to WFFA winners in addition to the trophy and banner. 
I printed one of these:
