This is a robust and surprisingly well working bearing. The design lets you make your own functional bearing despite the relative low accuracy of a 3D printer. If you get too much or too less play then change the tolerance for rolling surfaces and print the rollers again.

It is printed in parts so some easy assembly is necessary. All print-in-place bearings that I tried have too much play to be really useful. They just have to have a larger play else the parts would stick together when print
