Christoph Laimer published another very useful project. He developed a fully 3D printable and working parametric slew bearings. Since they are developed to be sturdy they can be used in many different project where a simpler 3D printed ball bearing would fail.

Since the design is parametric, you can adapt it to fit your needs. One version even has conical bearings.
Project description:
Ball-bearings are very popular for 3d-printing. However they often fail for real applications. Using Fusion 360 I've created a parametric design of a "Crossed Roller Slew Bearing". The result is a pretty accurate and robust bearing. The bearing including the rollers is 3d-printed in separate parts. There are a few screws needed to clamp the two halves of the inner race together.
