What it does
- Prints fully assembled with all parts functional right off the build plate
- No assembly required, integrated support structure included in design
- Perfect for testing your printer's tolerances and mechanical builds
- Functional ball bearing for prototypes, jigs, and workshop projects
This fully assembled ball bearing is a clever print-in-place design that demonstrates the capabilities of modern 3D printing. The entire bearing prints in one go, complete with integrated support structures, so you get a working mechanical part without any assembly steps.
It's a practical tool for anyone building custom jigs, prototypes, or mechanical assemblies in their workshop. The design serves double duty as both a functional component and a benchmark test for your printer's ability to handle tight tolerances and moving parts.
Designed by Daniel Norée, this straightforward bearing design puts function first. Print it once and you're ready to spin, ideal for makers who need quick mechanical solutions or want to explore print-in-place mechanisms.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
