Offset Fidget Spinner

thingiverse

I couldn't find a perfectly balanced fidget spinner on Thingiverse that fit my needs, so I decided to create one myself. This custom design features a "keyring" on one side and a bearing on the other of the central bearing, which creates an imbalance allowing the user to manipulate it in many different ways. Print Settings: Printer: Hictop Prusa i3 MK2 Rafts: Not required Supports: None needed Resolution: 0.2-0.25mm for both parts Infill: 15-30% for both parts Notes: You'll need to print out one frame and four bearing caps. I suggest laying out all four (including spares if desired) in your slicer to facilitate cooling. PLA is the recommended material. Something about either the bearing cap model or Cura's slicing settings caused the jerk control to fail, resulting in skipped Y-axis timing belt movement on my Prusa i3 printer. To resolve this issue, I set the printer speed to 40% and adjusted it as needed during printing. Alternatively, you can use different bearing cap designs or omit them altogether, but using caps provides comfort and ease of use. Post-Printing Assembly: This design requires two 608ZZ bearings, medium-grit sandpaper, and a pair of pliers. 1. Use a strip of medium-grit sandpaper to smooth out the rounded hole for added comfort. 2. Press each bearing into its corresponding holes and then use pliers to force the edges flush with the frame. Be careful not to crush the metal between the inner and outer rings, as this may cause the bearing to malfunction. 3. Insert the caps into the bearings, applying gentle pressure until they fit snugly. If necessary, sand the edges of the triangular caps to ensure a secure fit. Note: I'm not familiar with bearing sizing (608 vs 608Z, etc.), so this design is specifically tailored for "608ZZ" bearings. You can purchase these from Amazon at an affordable price and enjoy their superior performance, as demonstrated by my own experience with cannibalized bearings from an old skateboard: https://www.amazon.com/gp/product/B002BBD6X4/
