thingiverse
Made this on request from fellow maker, it's based on my open wheel tri-spinner, http://www.thingiverse.com/thing:1969949 It requires three 608 ball bearings. Sketchup design file included. Please post a picture if you print one! Print Settings Printer: Geeetech Prusa i3 Pro B Rafts: No Resolution: 0.2 mm Infill: 20% (doesn't really matter) Post-Printing 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.
