3. Place the balls in the bottom part. You will have to push them down to the channel. The balls should move freely in the channel and shouldn't fall off if you flip the bottom part.
4. Get some rubber buttons. I used rubber feet used to protect furniture and walls from hitting them with doors. Any rubber feet/buttons will do as long as the spool will get extra friction. Put the rubber feet both on top and bottom part. To get the right placement check at which points spool touches the top part.
