Long Run Fidget Spinner

My spinning time record is 2min 6sek.Compact and heavy fidget spinner for smaller hands.Print profile has 99% infill in order to increase weight thus length of run.Current diameter of bearing fit is 22,1mm, may be too little/much for your printer and filament; for me it was a very tight fit.Incl. snap ring to fix bearing axially; if bearing fit is tight enough, there is potentially no need for it.Including slim caps.Caps can be screwed together with M3 (4mm length) insert and M3x6 countersunk bolt, but can also be just snapped together.One ball bearing equivalent to 608zz needed. Very important: if you have a 608 bearing with enclosure (polymere or metal sheet) you have to open it up and clean it out with WD40 and isopropanol. This improves the spinning time by multiple factors. Here a nice tutorial:
