Nested Bearing Fidget

thingiverse

Another fidget toy to add to the collection. I created a self-aligning bearing for another project and couldn't stop playing with it, so I built a fidget toy around it. The center two rings pop out of the main body when you turn the main ring at a 90-degree angle from the main body, allowing you to mess with that smaller fidget on its own. Update - Based on some comments, the clearances can be a little tight. I've made another version that doubles the clearances (V2). To compensate for how loose that would make the assembly, I also made it thicker. I have not printed this version, but all of the previous settings should still apply. Print Settings Printer: QIDI Tech I Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 20% Notes: The clearance between the parts is 0.010 inches (10 mils), which should be plenty to ensure that they don't fuse into each other. Post-Printing I found that the little bit of "squish" on the first layer keeps the bearings from moving smoothly, so I trim the edge where that happens post-printing. How I Designed This I used Solidworks.
