Open wheel four bearing fidget spinner

thingiverse

I've been trying to find an 'open wheel' spinner without success, so I made this one. It's a quick and easy print. Requires four 608 bearings. Sketchup design file included. Please post a picture if you print one! Update 161216: three bearing version available - http://www.thingiverse.com/thing:1974338 Update 170202: hole for center bearing is a bit bigger, allows for a better fit when printed with bigger nozzle. Better clearance for the outer bearings. The halves now join at the center line of the bearing. Updated version files: Fidget03.stl/.skp Print Settings Printer: Geeetech I3 Pro B Rafts: No Supports: No Resolution: 0.2 mm Infill: 20% (doesn't really matter) Post-Printing Assembly Slide the outer bearings on. Tip - degrease the bearings before assembly for low friction operation. Press the two plastic parts together. It should be a snug fit - moderate force required. Press the center bearing in. As the bearing is thinner than the complete part, I recommend using an extra bearing as offset when pushing it in. The parts snaps apart easily. You could glue it together for a more secure build.
