DIY 3D PRINTED EASY GLIDE CURTAIN RING WITH MARBLE ROLLER BEARINGS

Here is my 3d printed curtain ring that uses marble bearings to reduce the friction. These rings are smoother to pull and rolls over those bumps in telescoping curtain rods easily. The marbles snap into these spherical channels in the ring.
The marbles were bought from walmart at $3 for 50 so its pretty cheap to make. However, I found that the marble sizes arent consistent (15 +/- 1mm) so some marbles couldnt be used.
I reused the clip from the old curtain rings.
