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.
