Aviator dual bar fidget spinner

The best dual bar fidget spinner I have created so far. The SS outer balls have a channel built into the body so the balls will spin freely. I uploaded 3 different STL files for different tolerances. I use an arbor press to press in the SS outer balls and the center bearing. I uploaded 3 STL files with different tolerances. My CR10 does best with the 5.92 file, if that is too tight, try the 5.96

The magnetic caps are excellent. Might require a slight sanding to fit smoothly into a 608 b
