Atom Tri bar fidget spinner

My favorite try bar spinner I have made. 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 12.92 file, if that is too tight, try the 12.94 or 12.96 file

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