Minimal Fidget Tri - Spinner

thingiverse

This is a 3 winged version of my Minimal In-Line Fidget Spinner. It uses the common 608 skateboard bearings. The three outer bearings just snap into place but make sure you support the arm it's on while fitting. The middle one also clips into place. It might be a little bit fiddly but this is necessary for it to be a firm fit. I have also included a central peg and caps. These work but I plan on improving them when I have time. I've noticed that there are very small differences in the inner diameter of the bearings so some require more force to fit than others depending on where you buy your bearings. The idea behind this design is to be minimal in the mateiral required and to be able to print, easily pop in the bearings and start fidgeting. Post-Printing Depending on your slicing software, you may have some slight stringing to tidy up on the inner edges of the outer pegs. Snap the three 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. My Other Fidget Spinners Pencil Top Fidget SpinnerDouble Decker Fidget SpinnerMinimal In-Line Fidget SpinnerSpeedy Car Fidget Spinner
