Minimal In-Line Fidget Spinner

thingiverse

My children wanted to play with a fidget spinner I'd printed from here but it was too big for their little hands so I set out to design the smallest one possible. These are the commonly used 608 bearings. The two outer bearings snap into place, just make sure you support the arm it's on while fitting. The middle one is held in by friction and a small lip on the underside. It also has the benefit of using very little material so it's ideal for short leftover filament. UPDATE: Added files: In_Line_Spinner_V2. It's more of a simple revision than another version. I've just knocked the inner corners off the snap pegs to make fitting easier and reduce the risk of breaking them while fitting. I've left the original files for reference. If you like this one, take a look at my Double Decker version. Print Settings Printer: Anet A8 Rafts: No Supports: No Resolution: 0.2 Infill: 100% Notes: I printed with 100% infill for maximum strength on the arms and snaps but I'm sure you could get away with less. It only took 15 minutes however to print at 100% infill so why not? Post-Printing Depending on your slicing software, you may have some slight stringing to tidy up on the inner edges of the out pegs. Snap the two outer bearings in place. If you have shielded bearings like the ones pictured, you will want to make a small modification to the middle one: Remove the shields, clean the bearing thoroughly and then lube with PTFE spray or similar. There are plenty of online tutorials of how to do this.
