I needed a thrust bearing for a lazy Susan and didn’t want to buy a metal one, so I designed my own in Fusion 360. The inner cage, outer body, and lid capture 10 loose cylinders that act as rolling elements.
All components can be printed support-free.
Make sure to print 10 units of the cylinder to fill all the slots in the cage.
This works as a thrust bearing for axial loads or as a lazy susan for displays, miniature turntables, etc. Just secure the base so it doesn’t move freely.
Assembly Instructions:
Place the cage inside the body.
Drop all 10 cylinders into the cage's channels.
Optional: Apply a tiny amount of grease to the inside of the lid or the cylinders for even smoother rotation.
Position the lid on top.
It may look like the lid won’t close—that’s normal! Apply firm, even pressure from one side to the other, and the lid will snap into place with a pressure fit. No glue, no tools, no hardware.
Printing Details:
No Supports Needed: All parts print flat and clean.
Nozzle: I used a 0.4mm nozzle on mine
Layer Height: 0.2–0.28 mm recommended for smoother rotation.
Filament: PLA works great; PETG adds a bit more flex for the snap-fit lid.
Print the cylinders vertically for the roundest profile and smoothest rolling action.
Hope you like it! If you do, please upload a make, I’d love to see it! 🙌
