Printable 6200 bearing with 6mm balls

thingiverse

The initial bearing accommodates 6,200 air-soft BBs yet has somewhat excessive play which might be suitable for certain uses; however, I plan to adjust its tightness. The updated version (v2) features tighter tolerances and less wobble; however, the races may require dressing. Smoothing it out by spinning in a fast drill can help. Using slic3r defaults at .3, I sliced the design for SD3 printing. A small half-round loading gate was added to the top rim's inside part for easy ball insertion. Air-soft 6mm ammo is required for completion.
