This is another design of printable ball bearings. But only the cage is printable - the balls you have to get yourselves!
I used little steel balls from a rainmaker toy from my daughter with a diameter of about 1.5 - 1.7 mm.
Because at this size the accuracy of my mendel has limits, I first printed a little filter with different hole sizes to select the right balls for the right hole diameter.
To make them fit into the hole inside the bearing, I had to set the radius of this hole to 1.83 mm for balls with a radius of 1.6 mm.
The openSCAD model is full parametric. So you can choose a ball size of your own - not everybody has a rainmaker toy at home^^
