You'll need twelve 5/32" (4mm) steel balls for this.

Print Settings

  • Layer height 0.2mm or less (0.1mm works better)
  • Random and/or scarf seams (reduces internal bumps

Assembly

  1. set the bottom half of the inner ring inside the outer ring
  2. push the balls into place
  3. push the top half of the inner ring onto the bottom half of the inner ring

I've included the OpenSCAD source in case you need to modify or remix.

Update: Added a smaller ring that uses 1/8" (3mm) balls.
