Fidget Spinner with BALLS

Made this little spinner for my wife. since she is a smaller person with Donald Trump like hands the bigger spinners were a little too big. This one takes 4 8mm steel bearings. Insert the bearings then the 608 bearing for the middle. I recommend printing a set or bearing caps for it. http://www.thingiverse.com/thing:1848330

There are 2 options to print. normal and beefy. I printed them out of PETG and noticed the normal would break if dropped.
